Sahih al-Bukhari 5684

Narrated Abu Sa`id Al-Khudri: A man came to the Prophet (ﷺ) and said, "My brother has some Abdominal trouble." The Prophet (ﷺ) said to him "Let him drink honey." The man came for the second time and the Prophet (ﷺ) said to him, 'Let him drink honey." He came for the third time and the Prophet (ﷺ) said, "Let him drink honey." He returned again and said, "I have done that ' The Prophet (ﷺ) then said, "Allah has said the truth, but your brother's `Abdomen has told a lie. Let him drink honey." So he made him drink honey and he was cured.
