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 it is not [possible] for one to die except by permission of Allah at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And we will reward the grateful. 145 And with how many a prophet have there been a number of devoted men who fought (beside him). They quailed not for aught that befell them in the way of Allah, nor did they weaken, nor were they brought low. Allah loveth the steadfast. 146 Nor did they say aught but: "O our Lord, forgive us our sins and excesses in our acts, and steady our steps, and help us against unbelieving people." 147 So Allah gave them the reward of this world and the best of rewards in the Hereafter; and Allah loves the righteous. 148
