۞ Allah is He Who shaped you out of weakness, then appointed after weakness strength, then, after strength, appointed weakness and grey hair. He createth what He will. He is the Knower, the Mighty. 54 And on the day when the Hour riseth the guilty will vow that they did tarry but an hour - thus were they ever deceived. 55 but those endowed with knowledge and faith will say, "Indeed, you did tarry, as God ordained, till the Day of Resurrection, and this is the Day of Resurrection: but you were not aware of it." 56 But on that day their excuse shall not profit those who were unjust, nor shall they be regarded with goodwill. 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 Thus does Allah seal the hearts of those who have no knowledge. 59 So be patient. Indeed, the promise of Allah is truth. And let them not disquiet you who are not certain [in faith]. 60
