It was narrated from Abu Salamah bin Abdur- Rahman that:

Abu Hurairah (led them in prayer and) recited: "When the heaven is split asunder." and prostrated during it. When he had finished praying, he told them that the Messenger of Allah ﷺ had prostrated during it.

أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ، قَرَأَ بِهِمْ { إِذَا السَّمَاءُ انْشَقَّتْ } فَسَجَدَ فِيهَا فَلَمَّا انْصَرَفَ أَخْبَرَهُمْ أَنَّ رَسُولَ اللَّهِ ﷺ سَجَدَ فِيهَا .
