۞ 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 And on the day when the Last Day is established, the guilty will swear that they did not stay except for an hour; this is how they keep straying. 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 Verily We have coined for mankind in this Qur'an all kinds of similitudes; and indeed if thou camest unto them with a miracle, those who disbelieve would verily exclaim: Ye are but tricksters! 58 As such Allah seals 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
