Musnad Ahmad 303:9

Yazid narrated to us, he said: Hammad ibn Salamah narrated to us, from Thabit al-Bunani, from Mutarrif ibn Abdullah, from his father, who said: "I saw the Messenger of Allah, may Allah bless him and grant him peace, and in his chest was a rumbling like the rumbling of a cooking pot, from weeping." Abdullah ibn Ahmad said: No one said "from weeping" except Yazid ibn Harun.
