Sayyiduna Abu Sa'id (may Allah be pleased with him) says that a man said: "O Prophet of Allah! My brother's stomach has become upset." He (peace and blessings be upon him) said: "Give him honey to drink." He came again and said: "O Messenger of Allah! It has become worse." He (peace and blessings be upon him) said: "Give him more to drink." On the third or fourth time he said: "Allah has spoken the truth, and your brother's stomach has lied; give him more honey." Then, after he was given honey, he recovered.
