Surah Ash Shu'ara Tafseer

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 نَزَّلْنَأ إِلَيْهِمُ الْمَلَـيِكَةَ 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 لَا يُوْمِنُونَ

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