obstruction from Allah's path

إِنَّ ٱلَّذِينَ كَفَرُوا۟ وَصَدُّوا۟ عَن سَبِيلِ ٱللَّهِ ثُمَّ مَاتُوا۟ وَهُمْ كُفَّارٌ فَلَن يَغْفِرَ ٱللَّهُ لَهُمْ

Indeed, those who disbelieved and averted [people] from the path of Allāh and then died while they were disbelievers - never will Allāh forgive them.

ٱتَّخَذُوٓا۟ أَيْمَـٰنَهُمْ جُنَّةً فَصَدُّوا۟ عَن سَبِيلِ ٱللَّهِ ۚ إِنَّهُمْ سَآءَ مَا كَانُوا۟ يَعْمَلُونَ

They have taken their oaths as a cover, so they averted [people] from the way of Allāh. Indeed, it was evil that they were doing.
