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. (Using translation from Nasāʾī 961)
أَنَّ أَبَا هُرَيْرَةَ قَرَأَ بِهِمْ {إِذَا السَّمَاءُ انْشَقَّتْ} [الانشقاق 1] فَسَجَدَ فِيهَا فَلَمَّا انْصَرَفَ أَخْبَرَهُمْ أَنَّ رَسُولَ اللهِ ﷺ سَجَدَ فِيهَا
