If a truthful narrator inserts a detail into the narration of a trustworthy narrator, does his addition take precedence over the trustworthy narrator’s narration, or is it said that the trustworthy narrator takes precedence over the truthful one?

The questioner : Shaykh, regarding the issue of insertion (idraj), some narrations are reported by trustworthy narrators in a connected form, without distinguishing whether a statement is from a Companion or a Successor. For example, a trustworthy narrator reports the hadith in a single continuous flow, and then a man who is less than trustworthy, such as one described as truthful, comes along and distinguishes certain parts of this hadith by saying, “The Messenger of Allah (peace and blessings be upon him) said so and so,” and adds, “Abu Hurayrah said so and so.” Does this truthful narrator’s narration take precedence over the first narration in the part he distinguished, or is it said that the trustworthy narrator takes precedence over the truthful one?

The Shaykh : Even if he were trustworthy, the first trustworthy narrator takes precedence.

The questioner : Even if he were trustworthy, the first trustworthy narrator takes precedence, given that there is someone who distinguished it.The Shaykh: Yes.
