صحيح البخاري

Narrated 'Ata:

We presented ourselves along with Ibn `Abbas at the funeral procession of Maimuna at a place called Sarif. Ibn `Abbas said, "This is the wife of the Prophet (ﷺ) so when you lift her bier, do not Jerk it or shake it much, but walk smoothly because the Prophet (ﷺ) had nine wives and he used to observe the night turns with eight of them, and for one of them there was no night turn."
