Musnad Ahmad 1085:1

Yazid narrated to us, Ibrahim ibn Sa'd informed us, my father informed me, he said: I was sitting next to Humayd ibn Abd al-Rahman in the mosque, and an elderly man from Banu Ghifar passed by, and in his ears was deafness, or he said: heaviness. Humayd sent for him, and when he approached, he said: "O son of my brother, make space for him between me and you, for he has accompanied the Messenger of Allah, may Allah bless him and grant him peace." So he came until he sat between me and him. Humayd said to him: "Narrate to me the hadith that you narrated to me from the Messenger of Allah, may Allah bless him and grant him peace." The elderly man said: I heard the Messenger of Allah, may Allah bless him and grant him peace, say: "Indeed, Allah forms the clouds, so it speaks the best of speech, and it laughs the best of laughter."
