Abu Rafi' · The Book of Mosques and Places of Prayer

I said the night prayer along with Abu Huraira and -as he recited:" When the heaven burst asunder," he performed prostration. Isaid to him: What prostration is this? He said: I prostrated myself (on this occasion of recital) behind Abu'I-Qasim (Muhammad. may peace be upon him), and Iwould go on doing this till I meet him (in the next world). Ibn 'Abu al-A'la said: (Abu Huraira uttered this: ) I would not abandon performing prostration.

I saw Abu Huraira performing prostration (while reciting this verse: )" When the heaven burst asunder." I said to him: Do you prostrate yourself (while reciting) i? He said: Yes, I saw my best Friend (ﷺ) prostrating himself on (the recital of this verse) and I shall continue prostrating till I meet him. Shu'ba asked: Do you mean (by Friend) the Messenger of Allah (ﷺ)? He said: Yes.
