Interpolated, Reversed, Extra-Link, Inconsistent, and Textually Altered Reports

Read-only question overview. Answers and scoring remain inside authenticated learner attempts.

• Which division correctly identifies the two main kinds of mudraj?
• A narrator’s gloss becomes inseparably joined to prophetic wording. Which category fits?
• Different teachers transmit portions through separate chains, but a pupil attributes the combined text to one uniform chain. What is defective?
• The opening comes from teacher A and the remainder from B, but only A’s chain is cited for the whole text. What is the proper diagnosis?
• A student heard report A indirectly and B directly from the senior teacher, but later narrates A as direct. What must be established?
• A teacher spoke before beginning a hadith, and the pupil treated the remark as prophetic text. Which boundary was lost?
• Where is matn interpolation often found, although it can occur elsewhere?
• How should Abū Hurayrah’s personal aspiration adjoining the double-reward report be classified?
• Why is the phrase “man kathurat ṣalātuhu bi’l-layl...” discussed here?
• Which inquiry is most useful when idrāj is suspected?
• A mawqūf gloss is established at the end of a sound prophetic report. What is the sound response?
• What distinguishes an interpolation from an acceptable addition by a reliable narrator?
• Which is a clear illustration of maqlūb in the chain?
• How does the reversal of “shimāluhu mā tunfiqu yamīnuhu” manifest?
• What most fundamentally separates mudraj from maqlūb?
• If altered reports are used temporarily to test a scholar’s memory, what safeguard matters?
• Which condition is especially important before deeming an intermediary superfluous in mazīd fī muttaṣil al-asānīd?
• The shorter chain uses only “ʿan”; another adds an intermediary. What is the responsible initial assessment?
• Two versions differ by an intermediary. Which conclusion is possible after investigation?
• What combination is required for a genuine ruling of iḍṭirāb?
• One of two conflicting chain variants is shown to be better preserved. What follows?
• Which statement about iḍṭirāb is more accurate?
• What kind of alteration especially illustrates muṣaḥḥaf?
• Which example best illustrates muḥarraf in this distinction?
• Every instance of idrāj necessarily proves deliberate fabrication by the narrator.
• Matn interpolation may occur at the start, middle, or end of a hadith.
• Every longer chain with an extra narrator is automatically mazīd fī muttaṣil al-asānīd.
• If variants can be reconciled or reliably preferred, disagreement alone does not prove iḍṭirāb.
• In this distinction, changes of dots and vowel marks necessarily bear the same technical name.
• Reversing a narrator’s name and his father’s name can affect identification and verification of an isnād.
