Musnad Ahmad Hadith 11147

Abu Saeed Khudri (may Allah be pleased with him) narrates that a man came to the Prophet (ﷺ) and said, "O Messenger of Allah (ﷺ), my nephew has diarrhea." The Prophet (ﷺ) said, "Go and give him honey to drink." He went and then came back and said, "I have given him honey to drink, but his illness has increased." The Prophet (ﷺ) said, "Go and give him honey to drink." He went and then came back and said, "I have given him honey to drink, but his illness has increased." For the third time, the Prophet (ﷺ) said, "Go and give him honey to drink." This time, he was cured. The Prophet (ﷺ) said, "Allah has spoken the truth, and your nephew's stomach has lied."
