Sahih Muslim Book 3, Hadith 28
← Previous Hadith I asked 'A'isha about the Witr (prayer) of the Messenger of Allah (ﷺ) 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).

Sahih Muslim Book 3, Hadith 27 Next Hadith → The Messenger of Allah (ﷺ) said: When anyone amongst you has sexual intercourse with his wife and then he intends to repeat it, he should perform ablution. In the hadith transmitted by Abu Bakr. (the words are):" Between the two (acts) there should be an ablution," or he (the narrator) said:" Then he intended that it should be repeated."
