اِنَّ الَّذِيْنَ يَكْتُمُوْنَ مَآ اَنْزَلْنَا مِنَ الْبَيِّنٰتِ وَالْهُدٰى مِنْۢ بَعْدِ مَا بَيَّنّٰهُ لِلنَّاسِ فِى الْكِتٰبِۙ اُولٰۤىِٕكَ يَلْعَنُهُمُ اللّٰهُ وَيَلْعَنُهُمُ اللّٰعِنُوْنَۙ ( البقرة: ١٥٩ )
Innal lazeena yaktumoona maaa anzalnaa minal baiyinaati walhudaa mim ba'di maa baiyannaahu linnaasi fil kitaabi ulaaa'ika yal'anuhumul laahu wa yal'anuhumul laa 'inoon (al-Baq̈arah 2:159)
Indeed, those who conceal what We sent down of clear proofs and guidance after We made it clear for the people in the Scripture – those are cursed by Allah and cursed by those who curse, (Al-Baqarah  : 159)
1 Mufti Taqi Usmani
Surely, those who conceal the clear signs and the guidance We have revealed, even after We have explained them for people in the Book, upon them Allah casts damnation, and they are cursed by all those who curse.
