Chapter : Forgetfulness in prayer and prostration as compensation for it.
Abu Rafi’ reported: I said the night prayer along with Abu Huraira and -as he recited: “When the heaven burst asunder,” he performed prostration. I said 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 I would 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.
