۞ 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 at the time when the hour shall come, the guilty shall swear (that) they did not tarry but an hour; thus are they ever turned away. 55 but those endowed with knowledge and faith will say, "Indeed, you did tarry, as God ordained, till the Day of Resurrection, and this is the Day of Resurrection: but you were not aware of it." 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 We have told people various parables in this Quran. Even if you had shown them a miracle, the unbelievers would have said, "You are only the followers of falsehood". 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 patiently persevere: for verily the promise of Allah is true: nor let those shake thy firmness, who have (themselves) no certainty of faith. 60
