Muhammad bin Sirin (may Allah have mercy on him) said: I was informed that Salim (may Allah be pleased with him), the freed slave of Abu Hudhayfah (may Allah be pleased with him), was freed by a woman of the Ansar (may Allah be pleased with her), and she said: Go and take as your patron whomever you wish. He took Abu Hudhayfah (may Allah be pleased with him) as his patron. When he was martyred, there was a dispute over his inheritance, and his inheritance was assigned to the Ansar.
