All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
Abu Umaamah narrated: “A woman who speaks to men in an obscene an vulgar manner passed by the Prophet while he was eating porridge and said: “Look at him, he eats in the same way a slave eats.” Hence, the Prophet said: ''I am the most devoted slave (to Allaah).” Then the woman said: “He eats and he does not offer food to me.” Thereupon, the Prophet told her: “Eat.” She said: “Feed me with your hand.” The Prophet did so. She said: “Give me from what you have in your mouth!’’ The Prophet gave her the food he had in his mouth. She ate and she became bashful and she never was obscene again to anyone until she died.” [At-Tabaraani]
This is the narration that mentions the story of the woman, however, Al-Haythami stated that its chain of narrators is weak, and thus it is an inauthentic narration.
Allaah Knows best.
