۞ 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 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 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 does Allah seal up the hearts of those who know not [the proofs and evidence of the Oneness of Allah i.e. those who try not to understand true facts that which you (Muhammad SAW) have brought to them]. 59 So be thou patient; surely God's promise is true; and let not those who have not sure faith make thee unsteady. 60
