۞ Allah creates you weak; after weakness He gives you strength and after strength weakness and gray hairs. He creates whatever He will. He is the Knower, the Capable. 54 And on the Day whereon the Hour arriveth, the culprits will swear that they tarried not but an hour; thus were they ever deluded. 55 But those endued with knowledge and faith will say: "Indeed ye did tarry, within Allah's Decree, to the Day of Resurrection, and this is the Day of Resurrection: but ye - ye were not aware!" 56 So on that Day their pleas shall be of no avail, nor will they be allowed to make amends. 57 Indeed, We have struck for the people in this Koran every manner of similitude; and if thou bringest them a sign, those who are unbelievers will certainly say, 'You do nothing but follow falsehood.' 58 Thus does Allah seal the hearts of those who have no knowledge. 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
