۞ 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 But those who were given the knowledge and belief will say: "You have tarried, according to the Book of God, as long as the Day of Resurrection, and this is the Day of Resurrection, but 'you do not know." 56 So on that Day no excuse of theirs will avail the transgressors, nor will they be invited (then) to seek grace (by repentance). 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 do not know. 59 Be patient. The promise of God is certainly true. Let not the faithless make you despair of the promise of God. 60
