Example in the Quran

إِنَّ ٱلَّذِينَ يَشۡتَرُونَ بِعَهۡدِ ٱللَّهِ وَأَيۡمَٰنِهِمۡ ثَمَنٗا قَلِيلًا أُوْلَٰٓئِكَ لَا خَلَٰقَ لَهُمۡ فِي ٱلۡأٓخِرَةِ وَلَا يُكَلِّمُهُمُ ٱللَّهُ وَلَا يَنظُرُ إِلَيۡهِمۡ يَوۡمَ ٱلۡقِيَٰمَةِ وَلَا يُزَكِّيهِمۡ وَلَهُمۡ عَذَابٌ أَلِيمٞ

Indeed, those who trade Allah’s covenant and their oaths for a fleeting gain will have no share in the Hereafter. Allah will neither speak to them, nor look at them, nor purify them on the Day of Judgment. And they will suffer a painful punishment.
