۞ It is God who created you of weakness, then after weakness gave you strength, then after strength will give you weakness and grey hair. Surely He makes whatever He wills. He is all-knowing and all-powerful. 54 Upon the Day when the Hour has come, the harmdoers will swear that they had stayed no more than an hour. As such they are deceived. 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 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 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 Thus does Allah set a seal on 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
