Muhammad is only a messenger. Messengers have passed away before him. If he should die, or be killed, will you turn back on your heels? Those who turn on their heels do not harm the Lord in the least. God will reward the grateful. 144 And no person can ever die except by Allah's Leave and at an appointed term. And whoever desires a reward in (this) world, We shall give him of it; and whoever desires a reward in the Hereafter, We shall give him thereof. And We shall 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 And Allah gave them the reward of this life, and the best reward of the Everlasting Life. Allah loves the gooddoers. 148
