On silence Except when Speaking what is Good, Abandonment of what does not concern one, and Slander — Hadith 22

22. Ibn Muskān said, and so did al-Ḥasan, “We heard Abā ʿAbdillāh (a) say, ‘A foul-mouthed woman once passed by the Messenger of Allah (ṣ) while he was eating, and said, ‘O Muḥammad, you are indeed eating the food of slaves sitting as a slave would sit. ’ So he (ṣ) said to her, ‘Woe be to you! And who is a more submissive slave [of Allah] than me? ’ She said, ‘Then share with me a morsel of your food. ’ So the Messenger of Allah (ṣ) gave her some of his food. She said, ‘No, by Allah. I want a morsel from your mouth to [enter] my mouth! ’ So he took out a morsel from his mouth and gave it to her, and she ate it. ” Abū ʿAbdillāh (a) said, “After that, she never uttered an obscene word until she left this world. ”
