Musnad Abu Ya'la al-Mawsili 42:288

Zuhayr narrated to us, Yazid bin Harun narrated to us, Shu'bah narrated to us, from Qatadah, from Abu al-Mutawakkil, from Abu Sa'id, who said: A man came to the Prophet, may Allah bless him and grant him peace, and said: "O Messenger of Allah, my brother's stomach has become loose." He said: "Give him honey to drink." He said: "So he gave him to drink." He said: "Then he came to him and said: 'I gave him honey to drink, and it did not increase him except in looseness.'" He said: "So he said: 'Give him honey to drink.' Then he came to him and said: 'I gave him to drink, and it did not increase him except in looseness.'" He said: "So he said: 'Give him honey to drink.'" He said: "Then, either on the third or the fourth time—I think he said—he was cured." He said: "So the Messenger of Allah, may Allah bless him and grant him peace, said: 'Allah has spoken the truth, and your brother's stomach has lied.'"
