Then Allah tells us how intense the disbelief of Quraysh was, and how stubbornly they resisted the Qur'an. If this Book with all its eloquence had been revealed to a non-Arab who did not know one word of Arabic, they still would not have believed in him. Allah says:

﴿وَلَوْ نَزَّلْنَـهُ عَلَى بَعْضِ الاٌّعْجَمِينَ ﴾

فَقَرَأَهُ عَلَيْهِم مَّا كَانُوا بِهِ مُؤْمِنِينَ-﴾

(And if We had revealed it unto any of the non-Arabs, And he had recited it unto them, they would not have believed in it.) And Allah says:

﴿وَلَوْ فَتَحْنَا عَلَيْهِم بَاباً مِّنَ السَّمَاءِ فَظَلُّواْ فِيهِ يَعْرُجُونَ لَقَالُواْ إِنَّمَا سُكِّرَتْ أَبْصَـرُنَا﴾

(And even if We opened to them a gate from the heaven and they were to keep on ascending thereto. They would surely say: "Our eyes have been dazzled...'') (15:14-15)

﴿وَلَوْ أَنَّنَا نَزَّلْنَآ إِلَيْهِمُ الْمَلَـئِكَةَ وَكَلَّمَهُمُ الْمَوْتَى﴾

(And even if We had sent down unto them angels, and the dead had spoken unto them...) (6:111)

﴿إِنَّ الَّذِينَ حَقَّتْ عَلَيْهِمْ كَلِمَةُ رَبِّكَ لاَ يُؤْمِنُونَ ﴾

(Truly, those, against whom the Word of your Lord has been justified, will not believe.) (10:96)

﴿كَذَلِكَ سَلَكْنَاهُ فِي قُلُوبِ الْمُجْرِمِينَ - لاَ يُؤْمِنُونَ بِهِ حَتَّى يَرَوُاْ الْعَذَابَ الاٌّلِيمَ - فَيَأْتِيَهُم بَغْتَةً وَهُمْ لاَ يَشْعُرُونَ - فَيَقُولُواْ هَلْ نَحْنُ مُنظَرُونَ - أَفَبِعَذَابِنَا يَسْتَعْجِلُونَ - أَفَرَأَيْتَ إِن مَّتَّعْنَـهُمْ سِنِينَ - ثُمَّ جَآءَهُم مَّا كَانُواْ يُوعَدُونَ - مَآ أَغْنَى عَنْهُمْ مَّا كَانُواْ يُمَتَّعُونَ - وَمَآ أَهْلَكْنَا مِن قَرْيَةٍ إِلاَّ لَهَا مُنذِرُونَ ﴾

ذِكْرَى وَمَا كُنَّا ظَـلِمِينَ-﴾

(200. Thus have We caused it to enter the hearts of the criminals.) (201. They will not believe in it until they see the painful torment.) (202. It shall come to them of a sudden, while they perceive it not.) (203. Then they will say: "Can we be respited'') (204. Would they then wish for Our torment to be hastened on) (205. Think, if We do let them enjoy for years,) (206. And afterwards comes to them that which they had been promised.) (207. All that with which they used to enjoy shall not avail them.) (208. And never did We destroy a township but it had its warners) (209. By way of reminder, and We have never been unjust.)
