Volume 7, Book 71, Number 614:
Narrated Abu Said:
A man came to the prophet and said, ‘My brother has got loose motions. The Prophet said, Let him
drink honey.” The man again (came) and said, ‘I made him drink (honey) but that made him worse.’
The Prophet said, ‘Allah has said the Truth, and the abdomen of your brother has told a lie.” (See
Hadith No. 88)
