وَإِذْ أَخَذَ ٱللَّهُ مِيثَٰقَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ لَتُبَيِّنُنَّهُۥ لِلنَّاسِ وَلَا تَكْتُمُونَهُۥ فَنَبَذُوهُ وَرَآءَ ظُهُورِهِمْ وَٱشْتَرَوْا۟ بِهِۦ ثَمَنًۭا قَلِيلًۭا ۖ فَبِئْسَ مَا يَشْتَرُونَ
And (remember) when Allah laid a charge on those who had received the Scripture (He said): Ye are to expound it to mankind and not to hide it. But they flung it behind their backs and bought thereby a little gain. Verily evil is that which they have gained thereby.
Surah Aal-i-Imraan(3:187)
