It was narrated that Abu Rafi’ said: “I prayed ‘Is prayer — meaning Al-’Atarnah behind Abu Hurairah and he recited: ‘When the heaven is split asunder’ and prostrated during it. When he had finished praying, I said: ‘Abu Hurairah, (this is) a prostration that we are not used to.’ He said: ‘Abu Al-Qasim did this prostration and I was (praying) behind him, and I will continue to do this prostration until I meet Abu Al-Qasim.” (Sahih)
