And surely We have explained matters to people in the Qur'an in diverse ways, using all manner of parables. But man is exceedingly contentious. 54 And naught preventeth mankind from believing when the guidance hath come unto them, and from asking foregiveness of their Lord, but that there may come unto them the dispensation of the ancients, or that the torment may come unto them face to face. 55 And We send not the Envoys, but good tidings to bear, and warning. Yet do the unbelievers dispute with falsehood, that they may rebut thereby the truth. They have taken My signs, and what they are warned of, in mockery. 56 And who does more wrong than he who is reminded of the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of his Lord, but turns away from them forgetting what (deeds) his hands have sent forth. Truly, We have set veils over their hearts lest they should understand this (the Quran), and in their ears, deafness. And if you (O Muhammad SAW) call them to guidance, even then they will never be guided. 57 And your Lord is the Forgiving, full of mercy. If He were to impose blame upon them for what they earned, He would have hastened for them the punishment. Rather, for them is an appointment from which they will never find an escape. 58 And these towns – We destroyed them when they committed injustice, and We had set an appointed time for their destruction. 59
