Umar ibn al-Khattab^[a] (Arabic: عُمَر بْن ٱلْخَطَّاب, romanized: ʿUmar ibn al-Khaṭṭāb; c. 582/583 – 644), also spelled Omar, was the second Rashidun caliph, ruling from August 634, when he succeeded Abu Bakr (r. 632–634) as the second caliph, until his assassination in 644.

Umar was a senior companion and father-in-law of the Islamic prophet Muhammad. Umar has been called instrumental in the expansion of the Islamic world beyond Arabia.

Umar initially opposed Muhammad, who was his distant Qurayshite kinsman and later became his son-in-law. However, after his conversion to Islam in 616, Umar became the first Muslim to openly pray at the Kaaba.

He participated in nearly all the battles and expeditions under Muhammad, who bestowed upon him the title al-Fārūq for his sound judgments. Followi Umar - World History Encyclopedia JATEC
