قُلۡ نَزَّلَهُۥ رُوحُ ٱلۡقُدُسِ مِن رَّبِّكَ بِٱلۡحَقِّ لِيُثَبِّتَ ٱلَّذِينَ ءَامَنُواْ وَهُدٗى وَبُشۡرَىٰ لِلۡمُسۡلِمِينَ
Say, [O Muhammad], "The Pure Spirit has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to the Muslims."
وَلَقَدۡ نَعۡلَمُ أَنَّهُمۡ يَقُولُونَ إِنَّمَا يُعَلِّمُهُۥ بَشَرٞۗ لِّسَانُ ٱلَّذِي يُلۡحِدُونَ إِلَيۡهِ أَعۡجَمِيّٞ وَهَٰذَا لِسَانٌ عَرَبِيّٞ مُّبِينٌ
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 يُؤۡمِنُونَ بِـَٔايَٰتِ ٱللَّهِ لَا يَهۡدِيهِمُ ٱللَّهُ وَلَهُمۡ عَذَابٌ أَلِيمٌ
Indeed, those who do not believe in the verses of Allah - Allah will not guide them, and for them is a painful punishment.
إِنَّمَا يَفۡتَرِي ٱلۡكَذِبَ ٱلَّذِينَ لَا يُؤۡمِنُونَ بِـَٔايَٰتِ ٱللَّهِۖ وَأُوْلَـٰٓئِكَ هُمُ ٱلۡكَٰذِبُونَ
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 بَعۡدِ إِيمَٰنِهِۦٓ إِلَّا مَنۡ أُكۡرِهَ وَقَلۡبُهُۥ مُطۡمَئِنُّۢ بِٱلۡإِيمَٰنِ وَلَٰكِن مَّن شَرَحَ بِٱلۡكُفۡرِ صَدۡرٗا فَعَلَيۡهِمۡ غَضَبٞ مِّنَ ٱللَّهِ وَلَهُمۡ عَذَابٌ عَظِيمٞ
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;
