2:27Those who violate God’s covenant after its confirmation, and sever what God has commanded to be joined, and commit evil on earth. These are the losers.

2:64But after that you turned away. Were it not for God’s grace and mercy towards you, you would have been among the losers.

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?

2:102And they followed what the devils taught during the reign of Salomon. It was not Solomon who disbelieved, but it was the devils who disbelieved. They taught the people witchcraft and what was revealed in Babylon to the two angels Harut and Marut. They did not teach anybody until they had said, “We are a test, so do not lose faith.” But they learned from them the means to cause separation between man and his wife. But they cannot harm anyone except with God's permission. And they learned what would harm them and not benefit them. Yet they knew that whoever deals in it will have no share in the Hereafter. Miserable is what they sold their souls for, if they only knew.

2:121Those to whom We have given the Scripture follow it, as it ought to be followed—these believe in it. But as for those who reject it—these are the losers.

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.
