From Anas ibn Malik who said: We were present for a daughter of the Messenger of Allah (SAW) [Umm Kulthum], and the Messenger of Allah was sitting on the grave, and I saw his eyes full of tears. He said: Is there any man among you who did not yield [i.e. have sex] last night? Abu Talha said: Me. He said: Go down. And he went down into her grave.
