۞ It is God who created you of weakness, then after weakness gave you strength, then after strength will give you weakness and grey hair. Surely He makes whatever He wills. He is all-knowing and all-powerful. 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 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 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 This is how Allah sets seal upon the hearts of the ignorant. 59 So be patient. Indeed, the promise of Allah is truth. And let them not disquiet you who are not certain [in faith]. 60
