An imam who recites a surah containing a verse of prostration and does not prostrate

Abu Khaldah said: I told Abu al-Aliyah, "I prayed in the mosque of such-and-such people; their imam recited a verse of prostration but did not prostrate." Abu al-Aliyah said, "Why did you not prostrate?"

Abd al-Rahman al-A'raj said: Sayyiduna Abu Hurayrah (may Allah be pleased with him) used to prostrate in Surah al-Inshiqaq. If he was praying behind someone and the imam recited Surah al-Inshiqaq and did not prostrate, Sayyiduna Abu Hurayrah would bow his head as a gesture.

Abu Amr, the freedman of al-Muttalib, said: On a Friday I was sitting in the mosque with Sayyiduna Ibn Umar (may Allah be pleased with them both), beside the chamber of Sayyidah Aishah (may Allah be pleased with her). Tariq was delivering the sermon to the people. He recited Surah al-Najm. Hearing it, Sayyiduna Ibn Umar (may Allah be pleased with them both) prostrated, and we prostrated too. And that wretched one (Tariq, the preacher) did not move.
