It is narrated from a person of Banu Sulayt that once I came to the service of the Prophet (peace be upon him) to discuss those captives of mine who had been captured during the time of ignorance. At that time, the Prophet (peace be upon him) was sitting and people had formed a circle around him. The Prophet (peace be upon him) was wearing a thick waistcloth. The Prophet (peace be upon him) was gesturing with his fingers. I heard him saying: "A Muslim is the brother of a Muslim; he does not oppress him nor does he leave him helpless. Taqwa is here," and he pointed with his hand towards his chest.
