۞ It is Allah Who created you in a state of (helpless) weakness, then gave (you) strength after weakness, then, after strength, gave (you weakness and a hoary head: He creates as He wills, and it is He Who has all knowledge and power. 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 But those who [in their lifetime] were endowed with knowledge and faith will say: "Indeed, you have been tardy in [accepting as true] what God has revealed, [and you have waited] until the Day of Resurrection: this, then, is the Day of Resurrection: but you - you were determined not to know it! 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 And We have certainly presented to the people in this Qur'an from every [kind of] example. But, [O Muhammad], if you should bring them a sign, the disbelievers will surely say, "You [believers] are but falsifiers." 58 Even so God seals the hearts of those that know 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
