۞ 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 So that will be the Day when the excuses of the wrong-doers will not avail them, nor will they be asked to make amends. 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 way God seals the hearts of those who do not [want to] know [the truth], 59 So have patience. The promise of God is surely true; and let not those who do not believe make you relax (your endeavours). 60
