2:76And when they come across those who believe, they say, “We believe,” but when they come together privately, they say, “Will you inform them of what God has disclosed to you, so that they might dispute with you concerning it before your Lord?” Do you not understand?

2:267O you who believe! Give of the good things you have earned, and from what We have produced for you from the earth. And do not pick the inferior things to give away, when you yourselves would not accept it except with eyes closed. And know that God is Sufficient and Praiseworthy.
