Shiavault - a Vault of Shia Islamic Books Caliphate and Imamate ‘Umar’s Caliphate Abu Bakr did not view the caliphate as an elective office; it is only natural that he appointed 'Umar his successor without prior consultation. Only after he had decided to appoint him, he asked 'Abd al-Rahman b. 'Awf and 'Uthman for their opinions. The former expressed 'Umar's well known harshness.
'Uthman more diplomatically answered that 'Umar's inside was better than his outside.[^1] Talha protested against the choice of him because of 'Umar's ill treatment of the people even during Abu Bakr's reign. Abu Bakr angrily rejected this criticism, declaring that 'Umar was the best of God's people.[^2] Abu Bakr owed him a considerable debt. 'Umar had made the coup at the Saqifa in his favor possible and had brought Medina firmly under control for him.
Above all, in Abu Bakr's behalf he had deprived the Prophet's household ( ahl al-bayt ) of their legitimate rights. When 'Umar came to power in 13/634, first he dismissed Khalid b. Walid and appointed Abu 'Ubayda as supreme commander of the Muslim armies in Syria. In Iraq, he commissioned Abu 'Ubayda b. Mas'ud Thaqafi with the general command. A year after Abu 'Ubayda b. Mas'ud was killed in battle, the caliph appointed Sa'd b. Abi Waqqas, the early Meccan Companion, as the supreme commander.
Under Sa'd, the decisive battle of Qadisiyya was won, Mesopotamia was completely subdued, Kufa was founded and Iran invaded. When Abu 'Ubayda died in the plague of 'Amwas in 18/639, the caliph appointed Yazid b. Abi Sufyan governor of Damascus, Jordan and Palestine. Shortly afterwards Yazid, too, died of the plague, and 'Umar appointed his brother Mu'awiya b. Abi Sufyan as his successor and governor of Damascus.
'Umar made every effort to bring about the reconciliation with the Banu Hashim without compromising the essential right of all Quraysh to the caliphate. He thus treated 'Ali basically, like the other . He displayed his favor for the Prophet's kin rather in courting 'Abbas who posed no political threat since he did not belong to the early and had no personal ambitions. 'Umar also drew 'Abd Allah b. 'Abbas, who was too young to pose a political threat, near to him.
Ibn 'Abbas was closely associated with 'Umar from the beginning to the end of his caliphate and he has left the most revealing reports about the caliph's private thoughts.
