Prophet Muhammad(PBUH)would accept invitations to meals from women Companions

‘My mother, Umm Sulaym, invited the Messenger of Allah, sallallaahu ‘alay- hi wa sallam, to a dinner which she had prepared. He (the Messenger of Allah, sallallaahu ‘alayhi wa sallam) ate out of that and then said: “Stand up so that I may pray.” ‘I picked up a mat (belonging to us) which had turned dark on account of its long use (or the lack of usage). I sprinkled water over it (in order to soften it and cleaned it from the dust that had accumulated on it). Then the Messenger of Al- lah, sallallaahu ‘alayhi wa sallam, stood upon it, and I and an orphan formed a row behind him, sallallaahu ‘alayhi wa sallam, and the old woman (i.e. his moth- er) was behind us, and the Messenger of Allah, sallallaahu ‘alayhi wa sallam, led us in two Rak’ahs (units) of prayer and then went back.’1
