Abu Huraira recited before them:" hen the heaven burst asunder" (al-Qur'an, lxxxiv. 1) and performed prostration. After completing (the prayer) he informed them that the Messenger of Allah ﷺ has prostrated himself at it (this verse).
أَنَّ أَبَا هُرَيْرَةَ قَرَأَ لَهُمْ { إِذَا السَّمَاءُ انْشَقَّتْ} فَسَجَدَ فِيهَا فَلَمَّا انْصَرَفَ أَخْبَرَهُمْ أَنَّ رَسُولَ اللَّهِ ﷺ سَجَدَ فِيهَا
