۞ Allah is He Who shaped you out of weakness, then appointed after weakness strength, then, after strength, appointed weakness and grey hair. He createth what He will. He is the Knower, the Mighty. 54 On the day when the Hour of Doom comes, the criminals will swear that they have remained (in their graves) for no more than an hour. They had been inventing lies in this way. 55 Those who have received knowledge and have faith will say, "By the decree of God, you have remained for the exact period which was mentioned in the Book of God about the Day of Resurrection. This is the Day of Resurrection, but you did not know." 56 So on that Day no excuse of theirs will avail the transgressors, nor will they be invited (then) to seek grace (by repentance). 57 And We have certainly presented to the people in this Qur'an from every [kind of] example. But, [O Muhammad], if you should bring them a sign, the disbelievers will surely say, "You [believers] are but falsifiers." 58 Thus does Allah set a seal on the hearts of those who do not know. 59 Therefore, (O Prophet), have patience. Surely Allah's promise is true. Let those who lack certainty not cause you to be unsteady. 60
