And verily We have displayed for mankind in this Qur'an all manner of similitudes, but man is more than anything contentious. 54 And nothing has prevented the people from believing when guidance came to them and from asking forgiveness of their Lord except that there [must] befall them the [accustomed] precedent of the former peoples or that the punishment should come [directly] before them. 55 We only send the messengers to bring good news and to give warning. Those who deny use fallacious arguments to nullify the truth, treating My revelations and My warnings as a jest. 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 But your Lord is Most forgiving, full of Mercy. If He were to call them (at once) to account for what they have earned, then surely He would have hastened their punishment: but they have their appointed time, beyond which they will find no refuge. 58 And these towns (population, 'Ad, Thamud, etc.) We destroyed when they did wrong. And We appointed a fixed time for their destruction. 59
