۞ 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 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 who were given the knowledge and belief will say: "You have tarried, according to the Book of God, as long as the Day of Resurrection, and this is the Day of Resurrection, but 'you do not know." 56 Their excuses will be of no avail to the sinners on that day, and they will not be allowed to beg for favour. 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 Thus does Allah seal up the hearts of those who understand not. 59 Therefore, (O Prophet), have patience. Surely Allah's promise is true. Let those who lack certainty not cause you to be unsteady. 60
