۞ 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 the Last Hour arrives, the evil-doers will swear they have not even tarried for an hour, they have always been 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 The excuses of the unjust on this day will be of no avail to them and they will not be able to please God. 57 And indeed We have set forth for mankind, in this Quran every kind of parable. But if you (O Muhammad SAW) bring to them any sign or proof, (as an evidence for the truth of your Prophethood), the disbelievers are sure to say (to the believers): "You follow nothing but falsehood, and magic." 58 In this wise Allah sealeth the hearts of those who believe not. 59 Therefore, (O Prophet), have patience. Surely Allah's promise is true. Let those who lack certainty not cause you to be unsteady. 60
