Musnad Ahmad 32:104

Ibn Abi ‘Adi narrated to us, from Humayd, from Anas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Do not ask me about anything until the Day of Resurrection, but I will tell you about it." ‘Abdullah ibn Hudhafah said: "O Messenger of Allah, who is my father?" He said: "Your father is Hudhafah." His mother said: "What did you intend by this?" He said: "I intended to find relief." It was said regarding him—and Humayd said: "I think this is from Anas"—that the Messenger of Allah (peace and blessings of Allah be upon him) became angry. ‘Umar said: "We are pleased with Allah as Lord, with Islam as a religion, and with Muhammad (peace and blessings of Allah be upon him) as a Prophet. We seek refuge in Allah from the anger of Allah and the anger of His Messenger."
