[A/I`mran 3:166] And the calamity that struck you on the day the two armies met, was by Allah’s command - and in order that He may make known the believers.
[A/I`mran 3:167] And in order to expose them who turned hypocrites; and it was said to them, “Come, fight in Allah's cause, or repel the enemy”; they answered, “If we knew how to fight, we would certainly have been with you”; and on that day they were nearer to open disbelief than to professed faith; they utter with their mouths what is not in their hearts; and Allah knows well what they hide. -
[A/I`mran 3:168] Those who spoke regarding their brothers while they themselves stayed back at home, “Had they listened to us, they would not have been slain”; say (to them, O dear Prophet Mohammed - peace and blessings be upon him), “Then avert your own death, if you are truthful!”
[A/I`mran 3:169] And do not ever assume that those who are slain in Allah's cause, are dead; in fact they are alive with their Lord, receiving sustenance. (Death does not mean extinction, it is the passing of the soul from this world to another. In case of virtuous believers, their bodies do not rot after death and they remain “alive”, in the manner Allah has ordained for them.)
[A/I`mran 3:170] Happy over what Allah has bestowed upon them from His grace, and rejoicing for those who will succeed them, and have not yet joined them; for on them is no fear nor any grief.
[A/I`mran 3:171] They rejoice because of the favours from Allah and (His) munificence, and because Allah does not waste the reward of the believers.
[A/I`mran 3:172] Those who responded to the call of Allah and His Noble Messenger after they had been grieved; for the virtuous and the pious among them is a great reward.
[A/I`mran 3:173] Those to whom the people said, “The people
have gathered against you, therefore fear them”, so their faith was further
increased; and they said, “Allah is Sufficient for us - and what an excellent
Trustee (of affairs) is He!”
