|عمر بن الخطاب|
ʿUmar ibn al-Khaṭṭāb (Arabic عمر بن الخطّاب), c. 586–590 – 644) c. 2 November (Dhu al-Hijjah 26, 23 Hijri), was a leading companion and adviser to the Islamic prophet Muhammad who later became the second Muslim Caliph after Muhammad's death.
Leader of the Muslim community after the death of Muḥammad ﷺ
A governor is accountable to his people. In his inauguration speech, Caliph ʿUmar ibn al-Khaṭṭāb (may Allāh be pleased with him) is reported to have said, “O Muslims, straighten me with your hands when I go wrong”. At that moment, a desert nomad stood up and said “O Leader of the Believers, if you’re not straightened by our hands, we’ll use our sword to straighten you!” Upon hearing this, Caliph ʿUmar said “I give thanks and praise to Allāh (al-ḥamdulillāh) that I have such subjects.”
Umar ibn Al-Khattāb, the 2nd caliph and rashidun, originally wanted to KILL the prophet! Umar, alongside others in Mecca, opposed Islam and threatened to kill Muhammad. He resolved to defend the traditional, polytheistic religion of Arabia. He was most adamant and cruel in opposing Muhammad and very prominent in persecuting the Muslims. Umar was the first man who resolved that Muhammad had to be murdered in order to finish Islam. Umar firmly believed in the unity of the Quraish and saw the new faith of Islam as a cause of division and discord among the Quraish. Considering the transformation Umar went through after hearing Surah Ta-Ha and his future place among the companions of Rasool, I would wager his repentance was accepted but of course it is all in the hands of Allah.
