أَخْبَرَنَا يَزِيدُ بْنُ هَارُونَ ، حَدَّثَنَا مُحَمَّدُ بْنُ عَمْرٍو ، عَنْ أَبِي سَلَمَةَ ، قَالَ : رَأَيْتُ أَبَا هُرَيْرَةَ يَسْجُدُ فِي إِذَا السَّمَاءُ انْشَقَّتْ ، فَقِيلَ لَهُ : تَسْجُدُ فِي سُورَةٍ مَا يُسْجَدُ فِيهَا؟ فَقَالَ : " إِنِّي رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَسْجُدُ فِيهَا "

Yazid bin Harun told us, Muhammad bin Amr told us, on the authority of Abu Salamah, he said: I saw Abu Hurairah prostrating when the sky split open, It was said to him: Do you prostrate in a surah? What is the prostration in? He said: “I saw the Messenger of God, may God bless him and grant him peace, prostrating in it.”
