الآية رقم (187) - وَإِذْ أَخَذَ اللّهُ مِيثَاقَ الَّذِينَ أُوتُواْ الْكِتَابَ لَتُبَيِّنُنَّهُ لِلنَّاسِ وَلاَ تَكْتُمُونَهُ فَنَبَذُوهُ وَرَاء ظُهُورِهِمْ وَاشْتَرَوْاْ بِهِ ثَمَناً قَلِيلاً فَبِئْسَ مَا يَشْتَرُونَ
(187) - {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.}
This is a rebuke to the Jews in al-Medina at the time of the Prophet (saws) and in every time, for Allah (swt) took the covenant from those who were given the Scripture that they must make it clear to the people and do not conceal the truth but they threw it behind their backs.
وَاشْتَرَوْاْ بِهِ ثَمَناً قَلِيلاً {exchanged it for a small price}: The whole worldly life is a small price for this denial and renunciation of what came in the Book of Allah (swt).
