Khalid, on his return from an expedition of Amida and Edessa was charged for embezzlement and thus was dismissed from army. Khalid's removal created a strong wrath among the people on the ground that Khalid, a national hero was mistreated by the Caliph and it was unjust to remove him from the army. In addition to this some supporters of Khalid embolden him to rebel against Umar's discriminatory decision but Khalid, though more than able to rebel chose to accept the decision.
