The Banū Hāshim (Arabic: بنو هاشم) is an Arab clan within the Quraysh tribe to which Muhammad (S.A.W) belonged, named after Muhammad’s (S.A.W) great-grandfather Hashim ibn Abd Manaf.
Members of this clan, and especially their descendants, are also referred to as Hashimids, Hashimites, or Hashemites, and often carry the surname al-Hāshimī. These descendants, and especially those tracing their lineage to Muhammad (S.A.W) through his daughter Fatima (A.S), hold the traditional title (often synonymous to Sayyid).[1]
