Musnad Abu Ya'la al-Mawsili 102:1

Hawtharah narrated to us, Hammad bin Salamah narrated to us, from Thabit al-Bunani, from Mutarrif bin Abdullah bin al-Shikhkhir, from his father, who said: I entered the mosque upon the Prophet, may Allah bless him and grant him peace, while he was standing, and from his chest was a rumbling like the rumbling of a cooking pot.
