۞ 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 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 to whom knowledge and belief have been given will say: 'You have stayed in the Book of Allah (the Protected Tablets) till the Day of Resurrection. This is the Day of Resurrection, yet you did not know' 56 So on that Day their pleas shall be of no avail, nor will they be allowed to make amends. 57 And We have certainly presented to the people in this Qur'an from every [kind of] example. But, [O Muhammad], if you should bring them a sign, the disbelievers will surely say, "You [believers] are but falsifiers." 58 Even so God seals the hearts of those that know not. 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
