Musnad Ahmad 1153:304

Ibn Numayr narrated to us, Yahya narrated to us, from ‘Amrah, from ‘Aishah, who said: When the news of the death of Ja‘far ibn Abi Talib, Zayd ibn Harithah, and ‘Abdullah ibn Rawahah came, the Messenger of Allah (peace and blessings of Allah be upon him) sat down, and sadness was recognizable on his face. ‘Aishah said: And I was looking through the crack of the door. A man came to him and said: "O Messenger of Allah, the women of Ja‘far..." and he mentioned their weeping. The Messenger of Allah (peace and blessings of Allah be upon him) ordered him to forbid them. The man went, then came back and said: "I have forbidden them, but they did not obey him." This continued until the third time, and she claimed that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Throw dust into their mouths." ‘Aishah said: I said: "May Allah rub your nose in the dust! By Allah, you will not do what he told you to do, nor will you leave the Messenger of Allah (peace and blessings of Allah be upon him) alone."
