Migration to Medina

When Abu Marsad, may Allah be pleased with him, and his son, Marsad migrated to Medina, both of them stayed with Hazrat Kulthum bin Al-Hadam. According to some, both of them stayed with Hazrat Sa‘d bin Haitham. Hazrat Abu Marsad was with the Holy Prophet (sa) in all the battles.
