Umm Salama informed 'Ata ibn Yasar that she served Allah’s Messenger (Allah bless him and give him peace) a grilled flank, so he ate from it, then embarked on the ritual prayer and did not perform the minor ritual ablution.
“I was a guest one night together with Allah’s Messenger (Allah bless him and give him peace), so he was brought a grilled flank. Then he took the blade and set about carving, and he carved some for me. Bilal arrived calling him to prayer, so he threw the blade away, and he said: ‘Why have his hands been soiled?’ His mustache hung down close to his mouth, so he said to him: ‘I shall clip it for you over a tooth-stick,’ or: ‘Clip it over a tooth-stick'!”
