Quran 3:77 from Surah Aal-i-Imraan on Divine Marvels.
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
English translation: Indeed those who exchange (the) Covenant (of) Allah and their oaths (for) a price little those no share for them in the Hereafter and not will speak to them Allah and not look at them (on the) Day (of) the Resurrection and not purify them and for them (is) a punishment painful
Transliteration: inna alladhina yashtaruna bi'ahdi al-lahi wa-aymanihim thamanan qalilan ulaika la khalaqa lahum fi al-akhirati wala yukallimuhumu al-lahu wala yanzuru ilayhim yawma al-qiyamati wala yuzakkihim walahum adhabun alimun
