Musnad Ahmad 759:5

Hassan ibn Musa narrated to us, Zuhair narrated to us, from Abdullah ibn Isa, from his father, from his grandfather, from Abu Layla, who said: I was with the Messenger of Allah, peace and blessings of Allah be upon him, and Al-Hasan or Al-Husayn was upon his chest or his stomach. He said: I saw his urine like streaks, so we stood up toward him. He said: "Leave my son, do not frighten him until he finishes his urine." Then he followed it with water. Then he stood up and entered the house of the charity dates, and the boy entered with him. He took a date and put it in his mouth, so the Prophet, peace and blessings of Allah be upon him, took it out and said: "Indeed, charity is not lawful for us." *** Abdullah ibn Muhammad narrated to us—and I heard it from Abdullah ibn Muhammad ibn Abi Shaybah—Ali ibn Hashim narrated to us, from Ibn Abi Layla, from Thabit, who said: I was sitting with Abd al-Rahman ibn Abi Layla in the mosque, and a large man came and said: "O Abu Isa!" He said: "Yes." He said: "Narrate to us what you heard regarding fur garments." He said: I heard my father say: I was sitting with the Prophet, peace and blessings of Allah be upon him, and a man came and said: "O Messenger of Allah, should I pray in fur garments?" He said: "Where is the tanning?" When he turned away, I said: "Who is this?" He said: "This is Suwayd ibn Ghafalah."
