۞ It is God who created you of weakness, then after weakness gave you strength, then after strength will give you weakness and grey hair. Surely He makes whatever He wills. He is all-knowing and all-powerful. 54 Upon the day when the Hour is come, the sinners shall swear they have not tarried above an hour; so they were perverted. 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 But on that day their excuse shall not profit those who were unjust, nor shall they be regarded with goodwill. 57 And indeed We have set forth for mankind, in this Quran every kind of parable. But if you (O Muhammad SAW) bring to them any sign or proof, (as an evidence for the truth of your Prophethood), the disbelievers are sure to say (to the believers): "You follow nothing but falsehood, and magic." 58 In this wise Allah sealeth the hearts of those who believe not. 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
