۞ 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 On the Day that the Hour (of Reckoning) will be established, the transgressors will swear that they tarried not but an hour: thus were they used to being deluded! 55 And those who have been vouchsafed knowledge and belief will say: assuredly ye have tarried according to the decree of Allah until the Day of Upraising; so this is the Day of Upraising, but ye were wont not to know. 56 So that Day, their excuse will not benefit those who wronged, nor will they be asked to appease [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 In this way does God seal the hearts of those who do not [want to] know [the truth]. 59 Therefore, (O Prophet), have patience. Surely Allah's promise is true. Let those who lack certainty not cause you to be unsteady. 60
