۞ Allah creates you weak; after weakness He gives you strength and after strength weakness and gray hairs. He creates whatever He will. He is the Knower, the Capable. 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 bestowed with knowledge and faith will say: "Indeed you have stayed according to the Decree of Allah, until the Day of Resurrection, so this is the Day of Resurrection, but you knew not." 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 In this way does God seal the hearts of those who do not [want to] know [the truth]. 59 So be patient. Indeed, the promise of Allah is truth. And let them not disquiet you who are not certain [in faith]. 60
