۞ 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 And those who are given knowledge and faith will say: Certainly you tarried according to the ordinance of Allah till the day of resurrection, so this is the day of resurrection, but you did not know. 56 And so, on that Day their excuse will be of no avail to those who were bent on evildoing, nor will they be allowed to make amends. 57 And indeed We have set forth for mankind, in this Quran every kind of parable. But if you (O Muhammad SAW) bring to them any sign or proof, (as an evidence for the truth of your Prophethood), the disbelievers are sure to say (to the believers): "You follow nothing but falsehood, and magic." 58 Thus does Allah seal up the hearts of those who know not [the proofs and evidence of the Oneness of Allah i.e. those who try not to understand true facts that which you (Muhammad SAW) have brought to them]. 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
