Isnād as Part of Religion: Transmitter Competence, Fitnah, and Connected Transmission

1. Isnād and the governing principle

بَابُ بَيَانِ أَنَّ الْإِسْنَادَ مِنَ الدِّينِ، وَأَنَّ الرِّوَايَةَ لَا تَكُونُ إِلَّا عَنِ الثِّقَاتِ، وَأَنَّ جَرْحَ الرُّوَاةِ بِمَا هُوَ فِيهِمْ جَائِزٌ بَلْ وَاجِبٌ، وَأَنَّهُ لَيْسَ مِنَ الْغِيبَةِ الْمُحَرَّمَةِ، بَلْ مِنَ الذَّبِّ عَنِ الشَّرِيعَةِ الْمُكَرَّمَةِ
Translation: The chapter explains that isnād is part of religion; reports are to be transmitted only from trustworthy narrators; pointing out the actual defects of transmitters is permissible—indeed obligatory—and is not forbidden backbiting, but rather part of defending the honoured Sharīʿah.

Jarḥ is evidence-based appraisal of a transmitter’s relevant defect, not personal disparagement. The criterion is reliable evidence about transmission, honesty or precision—not disagreement or insult.

This is the printed chapter heading in the edition containing al-Nawawī’s commentary, not a separate narration spoken by Imām Muslim or a Prophetic hadith.

2. Ibn Sīrīn: ascertain the source

حَدَّثَنَا حَسَنُ بْنُ الرَّبِيعِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ وَهِشَامٍ، عَنْ مُحَمَّدٍ، وَحَدَّثَنَا فُضَيْلٌ عَنْ هِشَامٍ، قَالَ: وَحَدَّثَنَا مُخَلَّدُ بْنُ حُسَيْنٍ، عَنْ هِشَامٍ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، قَالَ: «إِنَّ هَذَا الْعِلْمَ دِينٌ، فَانْظُرُوا عَمَّنْ تَأْخُذُونَ دِينَكُمْ».
Translation: Ḥasan b. al-Rabīʿ told us: Ḥammād b. Zayd told us, from Ayyūb and Hishām, from Muḥammad. Fuḍayl also narrated to us from Hishām; and Mukhlad b. Ḥusayn narrated to us from Hishām, from Muḥammad b. Sīrīn, who said: “This knowledge is religion, so examine from whom you take your religion.”

Here Muḥammad is Ibn Sīrīn and the first Hishām is Hishām b. Ḥassān, as al-Nawawī clarifies. The several routes identify how the Successor’s statement was transmitted; it is not a Prophetic report.

3. Why source selection matters

The issue is not whether a report sounds persuasive but how securely it is attributed. Honesty and precision are separate dimensions: an upright transmitter can still misremember.

The chain allows the reader to distinguish a Prophetic report from a Companion’s statement or a Successor’s legal judgment without indiscriminate suspicion.

4. Ibn Sīrīn on asking for isnād after fitnah

حَدَّثَنَا أَبُو جَعْفَرٍ مُحَمَّدُ بْنُ الصَّبَّاحِ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّاءَ، عَنْ عَاصِمٍ الْأَحْوَلِ، عَنِ ابْنِ سِيرِينَ، قَالَ: «لَمْ يَكُونُوا يَسْأَلُونَ عَنِ الْإِسْنَادِ، فَلَمَّا وَقَعَتِ الْفِتْنَةُ قَالُوا: سَمُّوا لَنَا رِجَالَكُمْ، فَيُنْظَرُ إِلَى أَهْلِ السُّنَّةِ فَيُؤْخَذُ حَدِيثُهُمْ، وَيُنْظَرُ إِلَى أَهْلِ الْبِدَعِ فَلَا يُؤْخَذُ حَدِيثُهُمْ».
Translation: Abū Jaʿfar Muḥammad b. al-Ṣabbāḥ related to us from Ismāʿīl b. Zakariyyāʾ, from ʿĀṣim al-Aḥwal, from Ibn Sīrīn, who said: “They did not use to ask about the chain of transmission. But when the fitnah occurred, they said: Name your transmitters for us. The people of the Sunnah were then examined and their reports accepted, while the people of innovations were examined and their reports not accepted.”

“They would not ask” describes an earlier general practice, not the claim that nobody ever checked a source. During and after turmoil the demand to name transmitters became systematic. This passage alone does not fix a single undisputed date for the fitnah.

5. Innovation and the qualifications of transmitter criticism

Ibn Sīrīn’s report describes a historical practice of distinguishing Ahl al-Sunnah from Ahl al-Bidaʿ when examining transmitters after the fitnah. The report’s general wording must be distinguished from the later technical analysis. In his earlier commentary on the Muqaddimah, al-Nawawī records the following positions.

1. He reports agreement that the narration of one whose innovation is judged by qualified scholarship to entail unbelief is not accepted. This does not authorize a verdict against a particular person based on a mere label or accusation.
2. On innovation not judged to entail unbelief, one position rejects such reports categorically, considering the fault in probity not removed by sincere interpretation.
3. Another accepts a narrator who does not consider lying permissible in support of his school, whether or not he actively advocates it. Al-Nawawī reports this as attributed to al-Shāfiʿī.
4. A third accepts the non-advocate but rejects the advocate of an innovation; al-Nawawī attributes it to many, perhaps most, scholars and calls it the fairest and soundest position.

The grounds concern the actual risk to truthful, accurate transmission, the nature of the innovation, and advocacy. Ibn Sīrīn’s words remain intact as the earlier historical testimony; assessment of any specific transmitter still demands evidence.

6. Ṭāwūs and the term malīʾ

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ، أَخْبَرَنَا عِيسَى، وَهُوَ ابْنُ يُونُسَ، حَدَّثَنَا الْأَوْزَاعِيُّ، عَنْ سُلَيْمَانَ بْنِ مُوسَى، قَالَ: لَقِيتُ طَاوُسًا، فَقُلْتُ: حَدَّثَنِي فُلَانٌ كَيْتَ وَكَيْتَ. قَالَ: «إِنْ كَانَ صَاحِبُكَ مَلِيًّا فَخُذْ عَنْهُ».
Translation: Isḥāq b. Ibrāhīm al-Ḥanẓalī told us: ʿĪsā b. Yūnus informed us: al-Awzāʿī told us, from Sulaymān b. Mūsā, who said: “I met Ṭāwūs and said, ‘So-and-so told me such-and-such.’ He replied, ‘If your informant is reliable and capable, take from him.’”

Malīʾ here does not mean financially wealthy. As al-Nawawī explains, it denotes a sufficiently trustworthy, precise and competent transmitter whose religion and knowledge support reliance on him.

7. Ṭāwūs through another chain

وَحَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ الدَّارِمِيُّ، أَخْبَرَنَا مَرْوَانُ، يَعْنِي ابْنَ مُحَمَّدٍ الدِّمَشْقِيَّ، حَدَّثَنَا سَعِيدُ بْنُ عَبْدِ الْعَزِيزِ، عَنْ سُلَيْمَانَ بْنِ مُوسَى، قَالَ: قُلْتُ لِطَاوُسٍ: إِنَّ فُلَانًا حَدَّثَنِي بِكَذَا وَكَذَا. قَالَ: «إِنْ كَانَ صَاحِبُكَ مَلِيًّا فَخُذْ عَنْهُ».
Translation: ʿAbd Allāh b. ʿAbd al-Raḥmān al-Dārimī told us: Marwān—that is, Ibn Muḥammad al-Dimashqī—informed us: Saʿīd b. ʿAbd al-ʿAzīz told us, from Sulaymān b. Mūsā, who said: “I said to Ṭāwūs, ‘So-and-so has narrated such-and-such to me.’ He answered, ‘If your informant is reliable and capable, take from him.’”

The routes share Sulaymān b. Mūsā → Ṭāwūs, while their earlier transmitters differ. Multiple routes can aid comparison, but their evidentiary value depends on genuine independence and reliability rather than merely the number of chains.

8. Trustworthiness is not identical to hadith competence

حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنَا الْأَصْمَعِيُّ، عَنِ ابْنِ أَبِي الزِّنَادِ، عَنْ أَبِيهِ، قَالَ: «أَدْرَكْتُ بِالْمَدِينَةِ مِائَةً كُلُّهُمْ مَأْمُونٌ، مَا يُؤْخَذُ عَنْهُمُ الْحَدِيثُ، يُقَالُ: لَيْسَ مِنْ أَهْلِهِ».
Translation: Naṣr b. ʿAlī related from al-Aṣmaʿī, Ibn Abī al-Zinād and his father: he met one hundred trustworthy people in Medina whose hadith was nevertheless not taken, for they were considered not sufficiently qualified in that discipline.

Maʾmūn praises personal trustworthiness; “not among its people” concerns suitability for specialized hadith transmission. Declining to use a pious person’s hadith does not entail accusing that person of lying.

9. Three distinct judgments

Keep three tests separate:
1. Is the transmitter honest?
2. Can that transmitter preserve and convey precise chains and wording?
3. How does this particular report compare with other evidence?

Success on the first test does not automatically settle the others. That is why personally trustworthy people could remain unsuitable for hadith transmission.

10. Saʿd b. Ibrāhīm: only reliable transmitters

حَدَّثَنِي مُحَمَّدُ بْنُ أَبِي عُمَرَ الْمَكِّيُّ، حَدَّثَنَا سُفْيَانُ، ح، وَحَدَّثَنِي أَبُو بَكْرِ بْنُ خَلَّادٍ الْبَاهِلِيُّ، وَاللَّفْظُ لَهُ، قَالَ: سَمِعْتُ سُفْيَانَ بْنَ عُيَيْنَةَ، عَنْ مِسْعَرٍ، قَالَ: سَمِعْتُ سَعْدَ بْنَ إِبْرَاهِيمَ، يَقُولُ: «لَا يُحَدِّثُ عَنْ رَسُولِ اللَّهِ ﷺ إِلَّا الثِّقَاتُ».
Translation: Muḥammad b. Abī ʿUmar al-Makkī told me: Sufyān narrated to us. [The chain then changes:] Abū Bakr b. Khallād al-Bāhilī told me—the wording is his—“I heard Sufyān b. ʿUyaynah, from Misʿar, who said: I heard Saʿd b. Ibrāhīm say: ‘Only trustworthy transmitters should narrate from the Messenger of Allah ﷺ.’”

This is Saʿd b. Ibrāhīm’s statement, not a Prophetic hadith. “The wording is his” identifies the second route as the source of these words. Thiqāt means transmitters whose reliability extends to the required accuracy of reporting.

11. Ibn al-Mubārak: isnād is part of religion

وَحَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ قُهْزَاذَ، مِنْ أَهْلِ مَرْوَ، قَالَ: سَمِعْتُ عَبْدَانَ بْنَ عُثْمَانَ، يَقُولُ: سَمِعْتُ عَبْدَ اللَّهِ بْنَ الْمُبَارَكِ، يَقُولُ: «الْإِسْنَادُ مِنَ الدِّينِ، وَلَوْلَا الْإِسْنَادُ لَقَالَ مَنْ شَاءَ مَا شَاءَ».
Translation: Muḥammad b. ʿAbd Allāh b. Quhzādh transmitted through ʿAbdān b. ʿUthmān that ʿAbd Allāh b. al-Mubārak said: “Isnād belongs to religion; without isnād anyone could say anything.”

A chain makes the claim of attribution examinable: contact and transmission can be investigated, narrators assessed and variants compared. The mere presence of names in a chain is not itself proof of authenticity.

12. Al-qawāʾim: the supports of a report

قَالَ: وَقَالَ مُحَمَّدُ بْنُ عَبْدِ اللَّهِ: حَدَّثَنِي الْعَبَّاسُ بْنُ أَبِي رِزْمَةَ، قَالَ: سَمِعْتُ عَبْدَ اللَّهِ، يَقُولُ: «بَيْنَنَا وَبَيْنَ الْقَوْمِ الْقَوَائِمُ»، يَعْنِي الْإِسْنَادَ.
Translation: Through al-ʿAbbās b. Abī Rizmah, Ibn al-Mubārak said: “Between us and the people stand the supports,” meaning the chains of transmission.

Qawāʾim evokes the legs or supports on which something stands. The image stresses that an attributable chain sustains the evidentiary claim; it is a metaphor, not a new technical condition separate from chain verification.

13. Ibn al-Mubārak tests a purported Prophetic report

وَقَالَ مُحَمَّدٌ: سَمِعْتُ أَبَا إِسْحَاقَ إِبْرَاهِيمَ بْنَ عِيسَى الطَّالَقَانِيَّ، قَالَ: قُلْتُ لِعَبْدِ اللَّهِ بْنِ الْمُبَارَكِ: يَا أَبَا عَبْدِ الرَّحْمَنِ، الْحَدِيثُ الَّذِي جَاءَ: «إِنَّ مِنَ الْبِرِّ بَعْدَ الْبِرِّ أَنْ تُصَلِّيَ لِأَبَوَيْكَ مَعَ صَلَاتِكَ، وَتَصُومَ لَهُمَا مَعَ صَوْمِكَ». قَالَ: فَقَالَ عَبْدُ اللَّهِ: يَا أَبَا إِسْحَاقَ، عَمَّنْ هَذَا؟ قَالَ: قُلْتُ لَهُ: هَذَا مِنْ حَدِيثِ شِهَابِ بْنِ خِرَاشٍ. فَقَالَ: ثِقَةٌ، عَمَّنْ؟
Translation: Muḥammad said: “I heard Abū Isḥāq Ibrāhīm b. ʿĪsā al-Ṭālaqānī say: I asked ʿAbd Allāh b. al-Mubārak, ‘O Abū ʿAbd al-Raḥmān, what of the report that has reached us: “Part of dutifulness after dutifulness is to pray on behalf of your parents alongside your own prayer, and to fast on their behalf alongside your own fast”?’ ʿAbd Allāh replied, ‘O Abū Isḥāq, from whom is this?’ I said, ‘It is from the narration of Shihāb b. Khirāsh.’ He replied, ‘He is trustworthy; from whom [did he receive it]?’”

The point is verifying attribution, not approving a report because its content sounds virtuous. Ibn al-Mubārak recognized one named transmitter as reliable while continuing to demand the next link.

14. The missing link and the “vast deserts”

قَالَ: قُلْتُ: عَنِ الْحَجَّاجِ بْنِ دِينَارٍ. قَالَ: ثِقَةٌ، عَمَّنْ؟ قَالَ: قُلْتُ: قَالَ رَسُولُ اللَّهِ ﷺ. قَالَ: يَا أَبَا إِسْحَاقَ، إِنَّ بَيْنَ الْحَجَّاجِ بْنِ دِينَارٍ وَبَيْنَ النَّبِيِّ ﷺ مَفَاوِزَ تَنْقَطِعُ فِيهَا أَعْنَاقُ الْمَطِيِّ، وَلَكِنْ لَيْسَ فِي الصَّدَقَةِ اخْتِلَافٌ.
Translation: On hearing al-Ḥajjāj b. Dīnār, Ibn al-Mubārak again said “Reliable.” But when the report jumped straight from him to the Prophet ﷺ, he described vast intervening distances that would exhaust mounts; regarding charity he noted no dispute.

Mafāwiz means remote stretches of desert; the image emphasizes the large break in transmission. Two trustworthy names cannot bridge an unmentioned link. The quoted devotional statement was introduced for criticism, not thereby authenticated as Prophetic.

15. Transmission criticism versus the separate juristic question

Ibn al-Mubārak’s words “But there is no disagreement concerning charity” separate two inquiries. The quoted report has a break between al-Ḥajjāj b. Dīnār and the Prophet ﷺ, while other evidence establishes benefit from charity given for the deceased. Al-Nawawī presents this benefit as agreed upon and explicitly rejects an exceptional opinion, reported by al-Māwardī, that the deceased can receive no posthumous benefit at all.

Prayer and fasting: in the general case, al-Shāfiʿī and the majority hold that the reward of prayer or fasting performed by another does not reach the deceased. If, however, the deceased owed an obligatory fast and a guardian or someone the guardian authorizes performs it, al-Shāfiʿī has two reported views: the more widely transmitted one denies validity, while later Shāfiʿī investigators consider the view permitting it stronger. This is distinct from voluntary fasting.

Qurʾān recitation: the well-known Shāfiʿī position is that its reward does not reach the deceased; some Shāfiʿī scholars disagree. Other groups extend the benefit to all devotional acts, including prayer, fasting and recitation, by analogy with supplication, charity and pilgrimage. Al-Nawawī rejects this unrestricted analogy as weak.

The restrictive argument invokes “A person shall have only what he strives for” (Qurʾān 53:39) and “When the child of Adam dies, his deeds cease except for three”; counterarguments appeal to the specific transmitted allowances concerning charity, supplication and pilgrimage. A legal view may rest on independent evidence, but none of these arguments repairs the disconnected isnād under discussion.

16. A named narrator and an explicit warning

وَقَالَ مُحَمَّدٌ: سَمِعْتُ عَلِيَّ بْنَ شَقِيقٍ، يَقُولُ: سَمِعْتُ عَبْدَ اللَّهِ بْنَ الْمُبَارَكِ، يَقُولُ عَلَى رُءُوسِ النَّاسِ: «دَعُوا حَدِيثَ عَمْرِو بْنِ ثَابِتٍ، فَإِنَّهُ كَانَ يَسُبُّ السَّلَفَ».
Translation: Muḥammad related through ʿAlī b. Shaqīq that Ibn al-Mubārak publicly warned: “Leave the reports of ʿAmr b. Thābit, for he used to revile the early generations.”

This is a historical criticism of a named transmitter, tied to stated conduct. The narrator-specific evidentiary judgment should not be mechanically generalized to every person whose theological views differ.

17. The method illustrated by the whole sequence

Taken together the reports teach a sequence: identify transmitters, assess honesty and precision separately, compare routes, examine contact or hearing, and weigh relevant evidence when routes differ.

“Isnād is part of religion” means attribution must be demonstrated through transmission, not inferred from attractive content. The following reports develop the rules for responsible narrator criticism.
