۞ Allah creates you weak; after weakness He gives you strength and after strength weakness and gray hairs. He creates whatever He will. He is the Knower, the Capable. 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 on that Day no excuse of theirs will avail the transgressors, nor will they be invited (then) to seek grace (by repentance). 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 Even so God seals the hearts of those that know not. 59 so have patience [O Muhammad]! God's promise is true; let not those who will not be convinced make you discouraged. 60
