What was the reaction of Abu Rafi' when he saw Abu Huraira prostrating during the recitation of "Idha s-samaa'u n-shaqqat" (84) after the `Isha' prayer behind Prophet Muhammad (saw)?
 Narrated Abu Rafi`:                     I offered the `Isha' prayer behind Abu Huraira and he recited, "Idha s-samaa'u n-shaqqat" (84) and prostrated. On my inquiring, he said, "I prostrated behind Abul-Qasim (the Prophet) (when he recited that Sura) and I will go on doing it till I meet him."
