Family tree of Umar

'Umar ibn al-Khattāb (c. 581 – 644), sometimes referred by Sunni Muslims as 'Umar al-Farooq ("the one who distinguishes between right and wrong") was from the Banu Adi clan of the Quraysh tribe. He was a companion of the Islamic prophet Muhammad and became the second Sunni Caliph (634 – 644) following the death of Abu Bakr, the first Caliph.

Many of Umar's relatives of the same generation were also Sahaba and his daughter Hafsa bint Umar was a Mother of the Believers. His sons were also an important Sahaba, and his grandsons were Salaf.
