۞ Allah it is Who created you in weakness, then He appointed strength after weakness, then after strength appointed weakness and grey hair. He createth whatsoever He listeth: and He is Knower, the Potent. 54 Upon the Day when the Hour has come, the harmdoers will swear that they had stayed no more than an hour. As such they are deceived. 55 But those endued with knowledge and faith will say: "Indeed ye did tarry, within Allah's Decree, to the Day of Resurrection, and this is the Day of Resurrection: but ye - ye were not aware!" 56 So that day their excuses will not profit the evildoers, nor will they be suffered to make amends. 57 verily We have propounded for men, in this Qur'an every kind of Parable: But if thou bring to them any Sign, the Unbelievers are sure to say, "Ye do nothing but talk vanities." 58 That is how God seals the hearts of those who do not know. 59 Therefore, (O Prophet), have patience. Surely Allah's promise is true. Let those who lack certainty not cause you to be unsteady. 60
