Caliph Abu Bakr's era
During Abu Bakr's reign as caliph, during which he remained occupied with Ridda wars, Umar was one of his chief advisers and secretary. Umar along with Khalid ibn Walid, probably was the architect and main strategist behind the collapse of rebellion in Arabia. Though at the beginning due to the apprehensive situation in Arabia Umar was opposing the military operations against the rebel tribes, possibly to enjoy their support in case of any possible foreign invasion by the Romans or the Persians, but later he seemed to agree with Abu Bakr's strategy to crush rebellion. Khalid ibn Walid by late 632 had successfully united Arabia after consecutive victories against rebels. Later during his own reign,Umar would mostly adopt the policy of avoiding wars and consolidating his power in the conquered land rather than expanding his empire through continuous warfare.[30] Prior to Battle of Yamamah, Umar pressured Abu Bakr to call back Khalid, who had killed Malik ibn Nuwayrah, a rebel chief who was a state criminal. Umar was reportedly misguided by Malik's brother that Malik was a Muslim and Khalid killed him because he wanted to marry his wife Layla bint al-Minhal, a renowned beauty in Arabia. While Abu Bakr refused to accept Umar's opinion and Umar continued insisting for Khalid's disposal even after Khalid's conquest of Iraq. It was Umar who advised Abu Bakr to compile Quran in the form of a book, after the death of 300 memorizers of Quran in Battle of Yamamah. Abu Bakr appointed Umar as his successor prior to his death in 634. He was confirmed in the office thereafter.
[edit] Appointment as a Caliph
Due to his strict and autocratic nature, Umar was not a very popular figure among the notables of Madinah and members of Majlis al Shura, accordingly succession of Umar was initially discouraged by high ranking companions of Abu Bakr.[31][32] When Abu Bakr was close to death, he nominated Umar to succeed him as the next Caliph.[33]Umar was still well known for his extraordinary will power, intelligence, political astuteness, impartiality, justice and care for poor and underprivileged people.[34] Abu Bakr is reported to have said to the high-ranking advisers:
Abu Bakr was fully aware of Umar's power and ability to succeed him. Succession of Umar was thus not as troublesome as any of the others. His was perhaps one of the smoothest transitions to power from one authority to another in the Muslim lands.[36] Abu Bakr before his death called Uthman to write his will in which he declared Umar his successor. In his will he instructed Umar to continue the conquests on Iraq and Syrian fronts. Abu Bakr's decision proved to be crucial in the strengthening of the nascent Islamic empire.His [Umar's] strictness was there because of my softness when the weight of Caliphate will be over his shoulders he will remain no longer strict. If I will be asked by the God to whom I have appointed my successor, I will tell him that I have appointed the best man among your men.[35]
[edit] Reign as Caliph
On 22 August Caliph Abu Bakr died. The same day Umar assumed the office of Caliphate. After the assumption of office as the Caliph, Umar addressed the Muslims in his Inaugural address as:O ye faithful! Abu Bakr is no more amongst us. He has the satisfaction that he has successfully piloted the ship of the Muslim state to safety after negotiating the stormy sea. He successfully waged the apostasy wars, and thanks to him, Islam is now supreme in Arabia. After Abu Bakr, the mantle of Caliphate has fallen on my shoulders. I swear it before God that I never coveted this office. I wished that it would have devolved on some other person more worthy than me. But now that in national interest, the responsibility for leading the Muslims has come to vest in me, I assure you that I will not run away from my post, and will make an earnest effort to discharge the onerous duties of the office to the best of my capacity in accordance with the injunctions of Islam. Allah has examined me from you and you from me, In the performance of my duties, I will seek guidance from the Holy Book, and will follow the examples set by the Holy Prophet and Abu Bakr. In this task I seek your assistance. If I follow the right path, follow me. If I deviate from the right path, correct me so that we are not led astray.
[edit] Initial challenges
Umar was already not an endearing figure in Medina. Although almost all of the Muslims had given pledge of loyalty to him, nevertheless he was rather more feared than loved. The first challenge for Umar was to win out his subjects and members of Majlis al Shura.[37] Umar was a gifted orator, and he would use his ability to get a soft corner in the hearts of people.[38] On Friday prayers Umar addressed the people as follows:Umar's addresses greatly moved the people. Next time he addressed the people as:Brethren, it has come to my notice that the people are afraid of me ... they say that he (Umar) has become the Caliph now, God knows how hard he will be. Whoever has said this is not wrong in his assessment ,,, know ye brethren that you will feel a change in me.[39] For those who practise tyranny and deprive others of their rights, I will be harsh and stern, but for those who follow the law, I will be most soft and tender.
I will be harsh and stern against the aggressor,[40] but I will be a pillar of strength for the weak.
The following are the historic words of Umar,[41] over which he laid foundation of his rule:I will not calm down until I will put one cheek of a tyrant on the ground and the other under my feet, and for the poor and weak, I will put my cheek on the ground.
Umar's stress was on the well being of poor and underprivileged people. As this class made a bulk of any community, the people were soundly moved by Umar's speeches and his popularity grew rapidly and continuously over the period of his reign.[43] In addition to this Umar, in order to improve his reputation and relation with Banu Hashim, the tribe of Prophet Muhammad and Ali, delivered to him his disputed estates in Khayber. Though he followed Abu Bakr's decision over the dispute of land of Fidak, continued its status as a state property. In Ridda wars, thousands of prisoners from rebel and apostate tribes were taken away as slaves during the expeditions. Umar ordered the general amnesty for the prisoners, and their immediate emancipation.[44] This made Umar quite a popular leader among the budoiene tribes. With necessary public support with him, Umar took a bold decision of retrieving Khalid ibn Walid from supreme command on Roman front.[45]By God, he that is weakest among you shall be in my eye the strongest,[42] until I have vindicated for him his rights; he that is strongest I will treat as the weakest, until he complies with the law.
