"Had We revealed it (Quran) to any of the non-Arabs, And had he recited it to them, they would not have believed in it. Thus have We caused it to enter the hearts of the sinners, they will not believe in it until they see the grievous Punishment; But that (Punishment) will come to them of a sudden, while they perceive it not; Then they will say: "Shall we be respited?" Do they then ask for Our Penalty to be hastened on? Seest thou? if We do let them enjoy (this life) for (a number of) years, yet there comes to them at length the (Punishment) which they were warned! so it will profit them not that (everything) they enjoyed before!"
