Ṣaḥīḥ li-dhātihi (صحیح لذاتہ) is a Hadith meeting five conditions:
• Every narrator is ʿādil: trustworthy and reliable.
• Every narrator is tāmm al-ḍabṭ: remembering or writing the Hadith very carefully with its sanad.
• The sanad is muttaṣil: no narrator is omitted.
• The report is not muʿallal: no hidden defect affects its soundness.
• The report is not shādhdh: a trustworthy narrator's report does not contradict a more reliable narrator's report.
