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 no human being can die save by God's leave, at a term pre-ordained. And if one desires the rewards of this world, We shall grant him thereof; and if one desires the rewards of the life to come, We shall grant him thereof; and We shall requite those who are grateful [to Us]. 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 all that they said was this: "O our Sustainer! Forgive us our sins and the lack of moderation in our doings! And make firm our steps, and succour us against people who deny the truth!" 147 So Allah gave them the reward of this world and the best of rewards in the Hereafter; and Allah loves the righteous. 148
