When all three generals appointed by the Prophet had been killed, the Muslims were left leaderless for a time. Then Khalid bin al-Walid who was also fighting in the ranks, seized the banner, and managed to rally the Muslims. At night the armies disengaged, and this gave him the opportunity to reorganize his men.
He is said to have fought a defensive action on the following day but realizing that it was impossible to win a victory, ordered a retreat from Mootah, and succeeded in bringing the remnants of the army back to Medina. When these warriors entered Medina, they got a “reception” that must have made them forget the “reception” that the Romans gave them in Mootah.
They were greeted by jeering crowds which cast dust in their faces and garbage on their heads, and taunted them for fleeing from the enemy instead of dying like men if not like heroes. Eventually, the Prophet himself was compelled to intervene on their behalf to rescue them from indignity and molestation. Sir William Muir The ranks of the Muslims were already broken; and the Romans in full pursuit made great havoc among the fugitives. So, distinctly, in the secretary of Wackidi.
Some accounts pretend that Khalid rallied the army, and either turned the day against the Romans, or made it a drawn battle. But besides that the brevity of all the accounts is proof enough of a reverse, the reception of the army on its return to Medina, admits of only one conclusion, viz. a complete, ignominious, and unretrieved discomfiture.
(The Life of Mohammed, London, 1861) Sir John Glubb In the battle of Mootah, Jaafer ibn Abu Talib, the brother of Ali, seized the banner from the dying Zaid and raised it aloft once more. The enemy closed in on the heroic Jaafer, who was soon covered with wounds. Tradition relates that when both his hands were cut off gripping the banner, he still stood firm, holding the staff between his two stumps, until a Byzantine soldier struck him a mortal blow.
When the defeated Muslims approached Medina, the Prophet and the people of the town went out to meet them. The citizens began to throw dirt at the crestfallen warriors, crying, “You runaways, you fled from the way of God!” But Mohammed, with that kind paternalism which he knew well how to use, interposed on their behalf.
