His descendants, the Banu al-Mughira, became the principle house of the Makhzum for the remainder of the pre-Islamic period and in the centuries following the advent of Islam in the 620s.
Al-Mughira was the son of Abd Allah ibn Umar and a great-grandson of the eponymous progenitor of the Banu Makhzum clan of the Quraysh tribe of Mecca.
[2] Al-Mughira was a contemporary of Abd al-Muttalib of the Quraysh's Banu Hashim clan and the grandfather of the Islamic prophet Muhammad.
[1] Anecdotes recorded by the 8th- and 9th-century historians Mus'ab al-Zubayri and al-Baladhuri mention that al-Mughira provoked a rebellion by the nomadic Banu Fazara tribe as a result of disbarring the Fazara's chieftain from making the pilgrimage to Mecca's religious sanctuary, the Ka'aba.
[3] The Makzhum became the Quraysh's strongest and wealthiest clan during the pre-Islamic period as a result of al-Mughira's leadership.
