Though Umar spent eighteen years in the company of Muhammad Mustafa, the Messenger of God, the latter never appointed him to any position of authority – civil or military. When the Apostle of God was on his deathbed, he asked the companions to bring pen, paper and ink so he might dictate his will but Umar defied him. He did not let the Apostle dictate his will and testament. Umar was not present at the funeral of the Prophet of Islam.
He was brawling with the Ansar in the outhouse of Saqifa when the body of the Prophet was being buried. Umar was the khalifa-maker of Abu Bakr. During Abu Bakr's khilafat, Umar was his principal adviser. The Banu Umayya were the traditional champions of idolatry and the arch-enemies of Muhammad and his clan, the Banu Hashim. Muhammad had broken their power but Umar revived them. The central component of his policy, as head of the government of Saqifa, was the restoration of the Umayyads.
He turned over Syria to them as their “fief,” and he made them the first family in the empire. A modern student of history might find claims made on behalf of some companions of the Prophet rather extravagant and baffling. He might notice in them the clash of popular imagination with historical reality.
But if he wishes to make a realistic evaluation of the roles they played in the lifetime of the Prophet, there is no better way of doing so than to turn away from rhapsody and rhetoric, and to focus attention on facts and facts alone. Principal Events of the Caliphate of Umar When Umar took charge of the caliphate, the Muslim armies were fighting against the Persians in Iraq and the Romans in Syria. The army in Syria was under the command of Khalid bin al-Walid, the favorite general of Abu Bakr.
Umar's first act as khalifa was to dismiss him from all his commands, and to appoint Abu Obaida bin al-Jarrah as the supreme commander of the Muslim forces in Syria. Shibli says that Umar had, for a long time, nursed a secret hatred of Khalid because of the latter's excesses. Umar had indeed dismissed Khalid because of his excesses but it appears that personal rancor was also at work. He was jealous of Khalid's fame and popularity.
If he disliked Khalid's transgressions, he ought to have formally indicted him, and should have ordered full investigation of his crimes in murdering Malik ibn Nuweira and in appropriating his widow. If Khalid had been proven guilty, then Umar ought to have passed sentence on him according to the Islamic law.
