۞ 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 And at the time when the hour shall come, the guilty shall swear (that) they did not tarry but an hour; thus are they ever turned away. 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 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 In this Koran We have set forth for mankind all manner of examples. Yet if you bring to them a sign the unbelievers will surely say: 'You are but falsifiers' 58 That is how God seals the hearts of those who do not know. 59 so have patience [O Muhammad]! God's promise is true; let not those who will not be convinced make you discouraged. 60
