۞ Allah it is Who created you in weakness, then He appointed strength after weakness, then after strength appointed weakness and grey hair. He createth whatsoever He listeth: and He is Knower, the Potent. 54 The day Resurrection is set the sinners will swear: "We did not tarry more than an hour (and cannot be guilty)." That is how they have always been deceived. 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 On that Day the excusing of themselves will not profit those who did wrong, nor shall they be suffered to please Allah. 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 God seal 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
