If then the Muslims attacked them...
If then the Muslims attacked them, they would be able to defend themselves and other tribes too might come to their rescue against the aggressors. Malik did not agree with his advice. Durayd said that then he would not have anything to do with the campaign! In fact Malik did not want his interference because he would claim credit if the battle was won by them! Therefore, rejecting a wise suggestion, the troops advanced forward to fight!
When the Prophet (a.s) learned that Banū-Hawazin and Banū-Thaqif were advancing for a battle with the Muslims, he deputed `Abdullah ibn Hadrad to reconnoiter about their movements. He returned after his investigations and reported to the prophet (a.s) that their intention to battle was very evident and that the Muslims must be ready to repulse their attack. The Prophet (a.s) called `Umar and told him what he had heard from Ibn Abi-Hadrad.
`Umar said Ibn Abi-Hadrad cannot be trusted because he is a liar. At this point Ibn Abi-Hadrad addressed `Umar and said: “O `Umar! If you are refuting me, you were used to refuting the Truth in the past”[1] The Prophet (a.s) trusted the intelligence of Ibn Abil-Hadrad and ordered the troops to be in readiness. They loaned from Safwan ibn Umayyah, who had not still embraced Islam, a hundred armors and other equipment of war and on 8 Shawwal 8H moved with 12,000 troops.
In this contingent there were 10,000 persons who had accompanied him from al-Madinah. The other 2,000 were the recent converts from Makkah. The numerical strength was thrice as much as that of the Infidels. This has created a subtle feeling of pride among the Muslims.
Therefore, seeing the strength of the army of Islam, Abū-Bakr said, “Today we shall not face defeat because of paucity of numbers!” The enemy arrived at the Valley of Hunayn and entrenched the men in the crevices and passages of the passages of the hills Hunayn is a valley lying on the hills between Makkah and Ta’if and had plain grounds on one side and ravines and ditches on the other.
When the Muslims reached the Valley of Hunayn in the morning, and advanced on the difficult and sloping terrain, the enemy started throwing stones and arrows on them. The Muslims did not expect this sudden attack on them. Pandemonium broke out in the troops. First the Front Guard flew! The commander of the group was Khalid ibn al-Walid! When those coming from behind saw Khalid running away, they too took to their heels!
