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]
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).
