Muhammad is only a messenger; and many a messenger has gone before him. So what if he dies or is killed! Will you turn back and go away in haste? But he who turns back and goes away in haste will do no harm to God. But God will reward those who give thanks (and are grateful). 144 And a soul will not die but with the permission of Allah the term is fixed; and whoever desires the reward of this world, I shall give him of it, and whoever desires the reward of the hereafter I shall give him of it, and I will reward the grateful. 145 And how many a prophet has had to fight [in God's cause,] followed by many God-devoted men: and they did not become faint of heart for all that they had to suffer in God's cause, and neither did they weaken, nor did they abase themselves [before the enemy,] since God loves those who are patient in adversity; 146 And they said nothing but: "Our Lord! Forgive us our sins and our transgressions (in keeping our duties to You), establish our feet firmly, and give us victory over the disbelieving folk." 147 So Allah gave them the reward of this world and the best of rewards in the Hereafter; and Allah loves the righteous. 148
