Ali-'Imran 166-175

Translation:

166. And what you suffered (of the disaster) on the day (of the battle of Uhud when) the two armies met, was by the leave of Allâh, in order that He might test the believers.

167. And that He might test the hypocrites, it was said to them: "Come, fight in the Way of Allâh or (at least) defend yourselves." They said: "Had we known that fighting will take place, we would certainly have followed you." They were that day, nearer to disbelief than to Faith, saying with their mouths what was not in their hearts. And Allâh has full knowledge of what they conceal.

168. (They are) the ones who said about their killed brethren while they themselves sat (at home): "If only they had listened to us, they would not have been killed." Say: "Avert death from your ownselves, if you speak the truth."

169. Think not of those who are killed in the Way of Allâh as dead. Nay, they are alive, with their Lord, and they have provision.

170. They rejoice in what Allâh has bestowed upon them of His Bounty, rejoicing for the sake of those who have not yet joined them, but are left behind (not yet martyred) that on them no fear shall come, nor shall they grieve.

171. They rejoice in a Grace and a Bounty from Allâh, and that Allâh will not waste the reward of the believers.

172. Those who answered (the Call of) Allâh and the Messenger (Muhammad SAW) after being wounded; for those of them who did good deeds and feared Allâh, there is a great reward.

173. Those (i.e. believers) unto whom the people (hypocrites) said, "Verily, the people (pagans) have gathered against you (a great army), therefore, fear them." But it (only) increased them in Faith, and they said: "Allâh (Alone) is Sufficient for us, and He is the Best Disposer of affairs (for us).[]"

174. So they returned with Grace and Bounty from Allâh. No harm touched them; and they followed the good Pleasure of Allâh. And Allâh is the Owner of Great Bounty.

175. It is only Shaitân (Satan) that suggests to you the fear of his Auliyâ' [supporters and friends (polytheists, disbelievers in the Oneness of Allâh and in His Messenger, Muhammad SAW)], so fear them not, but fear Me, if you are (true) believers.
