Bulugh al-Maram 340
Narrated Abu Hurairah (RA):
We prostrated with Allah's Messenger (ﷺ) (as he recited these Surah) "When the heaven split asunder" (Surah 84) and "Read in the Name of your Lord" (Surah 96). [Reported by Muslim).
وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- قَالَ : { سَجَدْنَا مَعَ رَسُولِ اَللَّهِ ‏- صلى الله عليه وسلم ‏-فِي : ( إِذَا اَلسَّمَاءُ اِنْشَقَّتْ )‏ , و : ( اِقْرَأْ بِاسْمِ رَبِّكَ )‏ } رَوَاهُ مُسْلِمٌ .‏ 1
