۞ 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 on the Day whereon the Hour arriveth, the culprits will swear that they tarried not but an hour; thus were they ever 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 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 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 Thus does Allah seal the hearts of those who do not know. 59 Therefore, (O Prophet), have patience. Surely Allah's promise is true. Let those who lack certainty not cause you to be unsteady. 60
