I offered the night prayer behind Abu Hurairah. He recited Surah Inshiqaq ("When the sky is rent asunder") and prostrated himself. I asked him: What is this prostration ? He replied: I prostrated myself on account of this (surah) behind Abu al-Qasim (i.e. the Prophet). I shall continue prostrating on account of this till I meet him. (Using translation from Abū Dāʾūd 1408)
صَلَّيْتُ مَعَ أَبِي هُرَيْرَةَ ؓ الْعَتَمَةَ فَقَرَأَ إِذَا السَّمَاءُ انْشَقَّتْ فَسَجَدَ قُلْتُ مَا هَذِهِ السَّجْدَةُ؟ قَالَ سَجَدْتُ بِهَا خَلْفَ أَبِي الْقَاسِمِ ﷺ فَلَا أَزَالُ أَسْجُدُ بِهَا حَتَّى أَلْقَاهُ وَرَوَاهُ الْبُخَارِيُّ فِي الصَّحِيحِ عَنْ مُسَدَّدٍ وَرَوَاهُ مُسْلِمٌ عَنْ عُبَيْدِ اللهِ بْنِ مُعَاذٍ وَغَيْرِهِ عَنْ مُعْتَمِرٍ
