Quraysh, the ruling tribe of Mecca at the time of the birth of the Prophet Muḥammad. There were 10 main clans, the names of some of which gained great lustre through their members’ status in early Islām. These included Hāshim, the clan of the Prophet himself (see Hāshimite); Zuhra, that of his mother; and Taim and ʿAdī, the clans of the first and second caliphs, Abū Bakr and ʿUmar I, respectively; and Umayya, the clan of the third caliph, ʿUthmān, and his relatives, the dynasty of the Umayyad caliphs.
