Here is a translation of the recited verses:

Muhammad is but an apostle; [other] apostles have passed before him. If he dies or is slain, will you turn back on your heels? Anyone who turns back on his heels, will not harm Allah in the least, and soon Allah will reward the grateful. (144) No soul may die except by Allah’s leave, at an appointed time. Whoever desires the reward of this world, We will give him of it; and whoever desires the reward of the Hereafter, We will give him of it; and soon We will reward the grateful. (145) How many a prophet there has been with whom a multitude of godly men fought. They did not falter for what befell them in the way of Allah, neither did they weaken, nor did they abase themselves; and Allah loves the steadfast. (146) All that they said was, ‘Our Lord, forgive us our sins and our excesses in our affairs, make our feet steady, and help us against the faithless lot.’ (147) So Allah gave them the reward of this world and the fair reward of the Hereafter; and Allah loves the virtuous. (148)
