Surah Aal-i-Imraan, Verse 187
وَإِذْ أَخَذَ ٱللَّهُ مِيثَٰقَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ لَتُبَيِّنُنَّهُۥ لِلنَّاسِ وَلَا تَكْتُمُونَهُۥ فَنَبَذُوهُ وَرَآءَ ظُهُورِهِمْ وَٱشْتَرَوْا۟ بِهِۦ ثَمَنًۭا قَلِيلًۭا ۖ فَبِئْسَ مَا يَشْتَرُونَ
Translation — Sahih International
And [mention, O Muhammad], when Allah took a covenant from those who were given the Scripture, [saying], "You must make it clear to the people and not conceal it." But they threw it away behind their backs and exchanged it for a small price. And wretched is that which they purchased.
