Hazrat Bilal narrates that his father, Hazrat Abu Burdah, said: Indeed, a man's maintaining ties of kinship with his father is that he maintains ties with his father's brothers, with whom his father himself maintained ties. Hazrat Hammad says: I think this is narrated from Hazrat Abu Musa, and Hazrat Hammad was asked whether Bilal bin Abu Burdah is meant. He replied: Yes.
