The discussion cites a report of Nu`aym al-Mujmir concerning prayer behind Abu Hurayrah, mentioning the opening «بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ». Its treatment raises the question of a reported additional detail about reciting aloud versus other reports that do not mention that detail.
Mentioning the basmalah and mentioning audible recitation of it are connected but separate claims. A narrator's failure to mention audibility is not by itself an explicit denial. At the same time, one must examine other preserved accounts and interpretive evidence before resolving a genuine disagreement.
The example illustrates the investigative difference between an addition, silence, and an actual conflict; it is not used here to impose a ruling in a disputed legal matter.
