Concealing
Remember when Allah took a covenant from those given the Scripture: ‘You must make it clear to people and not conceal it.’ But they cast it behind their backs and traded it for a small price. What a terrible bargain!
3:187And (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.
