Sunan Abi Dawud Book 2, Hadith 218
The Messenger of Allah (ﷺ) entered upon Umm Haram. The people (in her house) brought some cooking oil dates to him. He said; Put it (dates) back in its container and return it (cooking oil) to its bag, because I am keeping fast. He then stood and led us in prayer two Rak’ahs of supererogatory prayer. Then Umm Sulaim and Umm Haram stood behind us (i.e., the men). Thabit (the narrator) said: I understand that Anas said; he (the prophet) made me stand on his right side.
Messenger of Allah, our Imam is ill. He said : When he prays sitting, pray sitting.
Abu Dawud said : The chain of this tradition is not continuous (muttasil)
The Messenger of Allah (ﷺ) led him and one of their women in prayer. He (the prophet) put him on his right side and the woman behind him (Anas)
