What did the Prophet Muhammad (saw) do after engaging in sexual intercourse?
 'Abdullah b. Abu'l-Qais reported:                      I asked 'A'isha about the Witr (prayer) of the Messenger of Allah (may peace be upon him) 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. Some- times 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).
