Hazrat Abdur Rahman bin Azhar (may Allah be pleased with him) says that on the occasion of the Battle of Hunain, Hazrat Khalid bin Waleed (may Allah be pleased with him) was wounded. He was riding the horse of the Noble Prophet. After the defeat of the disbelievers, I saw the Noble Prophet (peace and blessings be upon him) walking among the Muslims who were returning from the battle, and he kept saying, "Who will show me the tent of Khalid bin Waleed?" At that time, I was an underage boy. I started running ahead of the Noble Prophet (peace and blessings be upon him), saying, "Who will show the tent of Khalid bin Waleed?" Until we reached his tent, where Hazrat Khalid (may Allah be pleased with him) was sitting, leaning against the back of his saddle. The Noble Prophet (peace and blessings be upon him) came and looked at his wound, then applied his blessed saliva to it.
