Qur'an 3:77

إِنَّ ٱلَّذِينَ يَشْتَرُونَ بِعَهْدِ ٱللَّهِ وَأَيْمَـٰنِهِمْ ثَمَنًا قَلِيلًا أُو۟لَـٰٓئِكَ لَا خَلَـٰقَ لَهُمْ فِى ٱلْـَٔاخِرَةِ وَلَا يُكَلِّمُهُمُ ٱللَّهُ وَلَا يَنظُرُ إِلَيْهِمْ يَوْمَ ٱلْقِيَـٰمَةِ وَلَا يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ

Lo! those who purchase a small gain at the cost of Allah's covenant and their oaths, they have no portion in the Hereafter. Allah will neither speak to them nor look upon them on the Day of Resurrection, nor will He make them grow. Theirs will be a painful doom.
