Chapter on the Manner of Prayer, Its Description and What is Obligatory and Recommended

Sa'd from Ahmad ibn Al-Hasan ibn Ali ibn Faddal from Amr ibn Sa'id from Musaddiq ibn Sadaqah from Ammar ibn Musa Al-Sabati: Abu Abdillah عليه السلام, peace be upon him, said regarding a man who hears a verse of prostration at a time when prayer is not valid, before the setting of the sun and after the prayer of Fajr. Imam عليه السلام said: "He does not prostrate." And (Imam عليه السلام said) regarding a man who recites in an obligatory prayer a Surah that contains a verse of prostration from the obligatory prostrations (al-‘Aza’im). Imam عليه السلام said: "When he reaches the place of the prostration, he should not recite it, and if he wishes, he may go back and recite another Surah and leave the one that contains the prostration, thus turning to another one." And (Imam عليه السلام said) regarding a man who prays among a group without following them and prays for himself, and they might recite a verse from the obligatory prostrations but they do not prostrate therein, what should he do? Imam عليه السلام said: "He does not prostrate."
