Surah An-Nisa, verse 138

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ ءَامِنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَٱلْكِتَـٰبِ ٱلَّذِى نَزَّلَ عَلَىٰ رَسُولِهِۦ وَٱلْكِتَـٰبِ ٱلَّذِىٓ أَنزَلَ مِن قَبْلُ ۚ وَمَن يَكْفُرْ بِٱللَّهِ وَمَلَـٰٓئِكَتِهِۦ وَكُتُبِهِۦ وَرُسُلِهِۦ وَٱلْيَوْمِ ٱلْـَٔاخِرِ فَقَدْ ضَلَّ ضَلَـٰلًۢا بَعِيدًا ﴿١٣٦﴾

O you who have believed, believe in Allāh and His Messenger and the Book that He sent down upon His Messenger and the Scripture which He sent down before. And whoever disbelieves in Allāh, His angels, His books, His messengers, and the Last Day has certainly gone far astray.

إِنَّ ٱلَّذِينَ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ ثُمَّ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ ثُمَّ ٱزْدَادُوا۟ كُفْرًۭا لَّمْ يَكُنِ ٱللَّهُ لِيَغْفِرَ لَهُمْ وَلَا لِيَهْدِيَهُمْ سَبِيلًۢا ﴿١٣٧﴾

Indeed, those who have believed then disbelieved, then believed then disbelieved, and then increased in disbelief - never will Allāh forgive them, nor will He guide them to a way.

ٱلَّذِينَ يَتَّخِذُونَ ٱلْكَـٰفِرِينَ أَوْلِيَآءَ مِن دُونِ ٱلْمُؤْمِنِينَ ۚ أَيَبْتَغُونَ عِندَهُمُ ٱلْعِزَّةَ فَإِنَّ ٱلْعِزَّةَ لِلَّهِ جَمِيعًۭا ﴿١٣٩﴾

Those who take disbelievers as allies instead of the believers. Do they seek with them honor [through power]? But indeed, honor belongs to Allāh entirely.

وَقَدْ نَزَّلَ عَلَيْكُمْ فِى ٱلْكِتَـٰبِ أَنْ إِذَا سَمِعْتُمْ ءَايَـٰتِ ٱللَّهِ يُكْفَرُ بِهَا وَيُسْتَهْزَأُ بِهَا فَلَا تَقْعُدُوا۟ مَعَهُمْ حَتَّىٰ يَخُوضُوا۟ فِى حَدِيثٍ غَيْرِهِۦٓ ۚ إِنَّكُمْ إِذًۭا مِّثْلُهُمْ ۗ إِنَّ ٱللَّهَ جَامِعُ ٱلْمُنَـٰفِقِينَ وَٱلْكَـٰفِرِينَ فِى جَهَنَّمَ جَمِيعًا ﴿١٤٠﴾

And it has already come down to you in the Book [i.e., the Qur’ān] that when you hear the verses of Allāh [recited], they are denied [by them] and ridiculed; so do not sit with them until they enter into another conversation. Indeed, you would then be like them. Indeed, Allāh will gather the hypocrites and disbelievers in Hell all together -
