۞ God is He that created you of weakness, then He appointed after weakness strength, then after strength He appointed weakness and grey hairs; He creates what He will, and He is the All-knowing, the 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 [in their lifetime] were endowed with knowledge and faith will say: "Indeed, you have been tardy in [accepting as true] what God has revealed, [and you have waited] until the Day of Resurrection: this, then, is the Day of Resurrection: but you - you were determined not to know it! 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 We have told people various parables in this Quran. Even if you had shown them a miracle, the unbelievers would have said, "You are only the followers of falsehood". 58 Thus does Allah seal up the hearts of those who understand not. 59 Therefore, have patience. The promise of Allah is true. Do not let those who are uncertain make you unsteady. 60
