After they returned from Uhud the Prophet s dispatched a group to seek out Abū Sufyān and his companions but they complained about their wounds and the following was revealed Be not faint be not weak in seeking in pursuing the enemy the disbelievers in order to fight them; if you are suffering if you have pains from a wound they are also suffering as you are suffering that is just like you yet they do not shrink from fighting you; and you hope from God in the way of victory and the reward for it that for which they cannot hope and since you have this advantage over them you should be more willing for it than them. God is ever Knower of all things Wise in His actions.
