'Abdullah bin Abu'l-Qais reported: I asked 'A'isha about the Witr (prayer) of the Messenger of Allah ( صلی اللہ علیہ وسلم ) and made mention of a hadith, then I said: What did he do after having sexual intercourse? Did he take a bath before going to sleep or did he sleep before taking a bath? She said: He did all these. Sometimes he took a bath and then slept, and sometimes he performed ablution only and went to sleep. I (the narrator) said: Praise be to Allah Who has made things easy (for human beings).

This hadith has been transmitted with the same chain of transmitters from Mu'awyia bin Salih by Zuhair bin Harb, 'Abdul Rahman bin Mahdi, Harun bin Sa'id al-'Aili and Ibn Wahb.
