Quran 2:159 from Surah Al-Baqara on Divine Marvels.
إِنَّ ٱلَّذِينَ يَكۡتُمُونَ مَآ أَنزَلۡنَا مِنَ ٱلۡبَيِّنَٰتِ وَٱلۡهُدَىٰ مِنۢ بَعۡدِ مَا بَيَّنَّٰهُ لِلنَّاسِ فِي ٱلۡكِتَٰبِ أُوْلَٰٓئِكَ يَلۡعَنُهُمُ ٱللَّهُ وَيَلۡعَنُهُمُ ٱللَّٰعِنُونَ
English translation: Indeed those who conceal what We revealed of the clear proofs and the Guidance from after [what] We made clear to the people in the Book those curses them Allah and curse them the ones who curse
Transliteration: inna alladhina yaktumuna ma anzalna mina al-bayinati wal-huda min ba'di ma bayyannahu lilnnasi fi al-kitabi ulaika yal'anuhumu al-lahu wayal'anuhumu al-la'inuna
