۞ God is He that created you of weakness, then He appointed after weakness strength, then after strength He appointed weakness and grey hairs; He creates what He will, and He is the All-knowing, the 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 But those to whom knowledge and belief have been given will say: 'You have stayed in the Book of Allah (the Protected Tablets) till the Day of Resurrection. This is the Day of Resurrection, yet 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 We have told people various parables in this Quran. Even if you had shown them a miracle, the unbelievers would have said, "You are only the followers of falsehood". 58 In this way does God seal the hearts of those who do not [want to] know [the truth]. 59 So be thou patient; surely God's promise is true; and let not those who have not sure faith make thee unsteady. 60
