Musannaf Ibn Abi Shayba 16:323

Abu Bakr narrated to us, he said: Abu al-Ahwas narrated to us, from Ata’ ibn al-Sa’ib, from his father, who said: I entered upon Ali on a cold day, and in his hand was a drink. He handed it to me and said, "Drink." I said, "What is it?" He said, "One-third honey, one-third ghee, and one-third milk." I said, "I do not want it." He said, "As for you, if you were to drink it, you would remain warm and full for the rest of your day."
