Imam Ali (a.
Imam Ali (a.s.) set out carrying with him monies which the Prophet (a.s.) had given to be paid as blood-money of the killed ones. Imam Ali (a.s.) paid to and recompensed them for everything even for a dog’s broken drinking vessel. Nothing of shed blood or damaged property remained except that Imam Ali (a.s.) paid money for it.
Some money remained with the Imam, but he gave it to them saying, “I give you the remainder of this money as a precaution for the messenger of Allah from what he does not know and what you do not know.” Imam Ali (a.s.) went back to the Prophet (a.s.) and told him of what happened.
The Prophet (a.s.) thanked him and said, “You have done well and right.” Then the Prophet (a.s.) raised his hands towards the heaven and said, “O Allah, I am free to you from what Khalid has done.” He said that three times. [1] [1] As-Seera an-Nabawiyyah by ibn Hisham, vol. 2 p. 429-430. This event shows that Khalid did not care for the Islamic morals. He did not regard any covenant. In fact he was eager to shed bloods.
His famous story with Malik bin Nuwayrah was another evidence that very clearly confirms this fact. 3. The battalion of Abdullah bin Rawaha The Prophet (a.s.) sent Abdullah bin Rawaha with thirty horsemen to Yusayr bin Rizam the Jew. The Prophet (a.s.) had been informed about the evil and the plotting of this villain Jew who was gathering people in order to fight against the Prophet (a.s.) and his companions.
When Abdullah bin Rawaha met Yusayr, he said to him, “The messenger of Allah has sent us to you (to tell you) that he has decided to appoint you the wali over Khaybar.” After insistence, he responded and went with the Muslims accompanied by thirty men from his people like the number of the Muslims accompanying Abdullah bin Rawaha.
When they arrived in Qarqarat Niyar (six miles from Khaybar), Yusayr regretted what he had done, and so he fell down to take the sword of Abdullah bin Rawaha who noticed that and he struck Yusayr’s leg and cut it. Yusayr hit Abdullah with a stick that was in his hand and he wounded his head. Then every Muslim attacked the Jew that was before him. All the Jews were killed except one who could run away, whereas no one of the Muslims was killed.
When Abdullah came back, the Prophet (a.s.) saw the wound in his head. He treated the wound with his saliva and it got well. [1] 4.
