How the bravery of hazrat umer impressed holy prophet hazrat muhammad

Umar initially opposed Muhammad, his distant Qurayshite kinsman and later son-in-law. Following his conversion to Islam in 616, he became the first Muslim to openly pray at the Kaaba. Umar participated in almost all battles and expeditions under Muhammad, who bestowed the title al-Faruq ('the Distinguisher') upon Umar, for his judgements. After Muhammad's death in June 632, Umar pledged allegiance to Abu Bakr (r. 632–634) as the first caliph and served as the closest adviser to the latter until August 634, when the dying Abu Bakr nominated Umar as his successor.

Under Umar, the caliphate expanded at an unprecedented rate, ruling the Sasanian Empire and more than two-thirds of the Byzantine Empire.[3] His attacks against the Sasanian Empire resulted in the conquest of Persia in less than two years (642–644). According to Jewish tradition, Umar set aside the Christian ban on Jews and allowed them into Jerusalem and to worship.[4] Umar was assassinated by the Persian slave Abu Lu'lu'a Firuz in 644.

Umar is generally viewed by historians to be one of the most powerful and influential Muslim caliphs in history.[5] He is revered in the Sunni Islamic tradition as a great just ruler and paragon of Islamic virtues,[6] and some hadiths identify him as the second greatest of the Sahabah after Abu Bakr.[7][8] He is viewed negatively in the Twelver Shia tradition.[9]
