Read Page 279 of the Quran

وَلَقَدْ نَعْلَمُ أَنَّهُمْ يَقُولُونَ إِنَّمَا يُعَلِّمُهُۥ بَشَرٌۭ ۗ لِّسَانُ ٱلَّذِى يُلْحِدُونَ إِلَيْهِ أَعْجَمِىٌّۭ وَهَـٰذَا لِسَانٌ عَرَبِىٌّۭ مُّبِينٌ ﴿103﴾

And We certainly know that they say, "It is only a human being who teaches the Prophet." The tongue of the one they refer to is foreign, and this Qur'an is [in] a clear Arabic language.

إِنَّ ٱلَّذِينَ لَا يُؤْمِنُونَ بِـَٔايَـٰتِ ٱللَّهِ لَا يَهْدِيهِمُ ٱللَّهُ وَلَهُمْ عَذَابٌ أَلِيمٌ ﴿104﴾

Indeed, those who do not believe in the verses of Allah - Allah will not guide them, and for them is a painful punishment.

إِنَّمَا يَفْتَرِى ٱلْكَذِبَ ٱلَّذِينَ لَا يُؤْمِنُونَ بِـَٔايَـٰتِ ٱللَّهِ ۖ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْكَـٰذِبُونَ ﴿105﴾

They only invent falsehood who do not believe in the verses of Allah, and it is those who are the liars.

مَن كَفَرَ بِٱللَّهِ مِنۢ بَعْدِ إِيمَـٰنِهِۦٓ إِلَّا مَنْ أُكْرِهَ وَقَلْبُهُۥ مُطْمَئِنٌّۢ بِٱلْإِيمَـٰنِ وَلَـٰكِن مَّن شَرَحَ بِٱلْكُفْرِ صَدْرًۭا فَعَلَيْهِمْ غَضَبٌۭ مِّنَ ٱللَّهِ وَلَهُمْ عَذَابٌ عَظِيمٌۭ ﴿106﴾

Whoever disbelieves in Allah after his belief... except for one who is forced [to renounce his religion] while his heart is secure in faith. But those who [willingly] open their breasts to disbelief, upon them is wrath from Allah, and for them is a great punishment;

ذَٰلِكَ بِأَنَّهُمُ ٱسْتَحَبُّوا۟ ٱلْحَيَوٰةَ ٱلدُّنْيَا عَلَى ٱلْـَٔاخِرَةِ وَأَنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلْكَـٰفِرِينَ ﴿107﴾

That is because they preferred the worldly life over the Hereafter and that Allah does not guide the disbelieving people.

أُو۟لَـٰٓئِكَ ٱلَّذِينَ طَبَعَ ٱللَّهُ عَلَىٰ قُلُوبِهِمْ وَسَمْعِهِمْ وَأَبْصَـٰرِهِمْ ۖ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْغَـٰفِلُونَ ﴿108﴾

Those are the ones over whose hearts and hearing and vision Allah has sealed, and it is those who are the heedless.

لَا جَرَمَ أَنَّهُمْ فِى ٱلْـَٔاخِرَةِ هُمُ ٱلْخَـٰسِرُونَ ﴿109﴾

Assuredly, it is they, in the Hereafter, who will be the losers.

ثُمَّ إِنَّ رَبَّكَ لِلَّذِينَ هَاجَرُوا۟ مِنۢ بَعْدِ مَا فُتِنُوا۟ ثُمَّ جَـٰهَدُوا۟ وَصَبَرُوٓا۟ إِنَّ رَبَّكَ مِنۢ بَعْدِهَا لَغَفُورٌۭ رَّحِيمٌۭ ﴿110﴾

Then, indeed your Lord, to those who emigrated after they had been compelled [to renounce their religion] and thereafter fought [for the cause of Allah] and were patient - indeed, your Lord, after that, is Forgiving and Merciful
