۞ 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 Upon the day when the Hour is come, the sinners shall swear they have not tarried above an hour; so they were perverted. 55 but those endowed with knowledge and faith will say, "Indeed, you did tarry, as God ordained, till the Day of Resurrection, and this is the Day of Resurrection: but you were not aware of it." 56 So that will be the Day when the excuses of the wrong-doers will not avail them, nor will they be asked to make amends. 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 This is how Allah sets seal upon the hearts of the ignorant. 59 Therefore, (O Prophet), have patience. Surely Allah's promise is true. Let those who lack certainty not cause you to be unsteady. 60
