When the Messenger of Allâh [pbuh] settled down in his head quarters in the hillock, the idolaters started their last attack upon the Muslims. Ibn Ishaq related that: "While the Prophet [pbuh] was on the way to the hillock, a group of Quraishite elite ascended the mountain. They were led by Khalid bin Al-Waleed and Abu Sufyan. So the Messenger of Allâh [pbuh] implored his Lord saying: ‘O Allâh, they (i.e. the idolaters) should not be higher (i.e. in position or in power) than us (i.e. the Muslims). Therefore ‘Umar bin Al-Khattab and some of the Emigrants fought the idolaters till they drove them down the mountain.[Ibn Hisham 2/86]
In Al-Maghazi — a book by Al-Umawi — it is stated that the idolaters went up the mountain. So the Messenger of Allâh [pbuh] said to Sa‘d: "Drive them off." "How can I drive them off by myself (i.e. without anyone to assist)." But the Messenger of Allâh [pbuh] repeated the phrase three times. Sa‘d then took an arrow out of his quiver, shot it at one of them and killed him. He said: "Then I took another one I know (to be good) and I shot with it another man. Then I took a third I know and killed a third one. Consequently they climbed down the mountain. I said to myself, ‘this must be a blessed arrow.’ I put it in my quiver." He kept it with him till he died. His children kept it with them ever after. [Za'd Al-Ma'ad 2/95]
