NASAI-KUBRA 1042:
from Abū Rāfiʿ —
"I prayed Isha' prayer- meaning Al-'Atamah behind Abu Hurairah and he recited: 'When the heaven is split asunder' and prostrated during it. When he had finished praying, I said: 'O Abu Hurairah, (this is) a prostration that we are not used to.' He said: 'Abu Al-Qasim ﷺ did this prostration and I was (praying) behind him, and I will continue to do this prostration until I meet Abu Al-Qasim. (Using translation from Nasāʾī 968)

عن ابو رافع —
صَلَّيْتُ خَلْفَ أَبِي هُرَيْرَةَ صَلَاةَ الْعِشَاءِ يَعْنِي الْعَتَمَةَ فَقَرَأَ إِذَا السَّمَاءُ انْشَقَّتْ فَسَجَدَ فِيهَا فَلَمَّا فَرَغَ قُلْتُ يَا أَبَا هُرَيْرَةَ هَذِهِ السَّجْدَةُ مَا كُنَّا نَسْجُدُهَا قَالَ «سَجَدَ بِهَا أَبُو الْقَاسِمِ ﷺ وَأَنَا خَلْفَهُ فَلَا أَزَالُ أَسْجُدُ بِهَا حَتَّى أَلْقَى أَبَا الْقَاسِمِ ﷺ»
