۞ 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 And those who have been bestowed with knowledge and faith will say: "Indeed you have stayed according to the Decree of Allah, until the Day of Resurrection, so this is the Day of Resurrection, but you knew not." 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, INDEED, We have propounded unto men all kinds of parables in this Qur'an. But thus it is: if thou approach them with any [such] message, those who are bent on denying the truth are sure to say: "You are but making false claims!" 58 In this way does God seal the hearts of those who do not [want to] know [the truth]. 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
