۞ 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 the Last Hour arrives, the evil-doers will swear they have not even tarried for an hour, they have always been deluded, 55 And said those who received knowledge and faith, “You have indeed stayed in the decree of Allah until the Day of Restoration; so this is the Day of Restoration, but you did not know.” 56 And so, on that Day their excuse will be of no avail to those who were bent on evildoing, nor will they be allowed 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 Thus does Allah seal the hearts of those who have no knowledge. 59 So be patient. Indeed, the promise of Allah is truth. And let them not disquiet you who are not certain [in faith]. 60
