۞ Allah is He Who shaped you out of weakness, then appointed after weakness strength, then, after strength, appointed weakness and grey hair. He createth what He will. He is the Knower, the Mighty. 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 [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 So on that Day no excuse of theirs will avail the transgressors, nor will they be invited (then) to seek grace (by repentance). 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 Thus doth Allah seal the hearts of those who 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
