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.

2:142The ignorant among the people will say, “What has turned them away from the direction of prayer they once followed?” Say, “To God belong the East and the West. He guides whom He wills to a straight path.”

2:143Thus We made you a moderate community, that you may be witnesses to humanity, and that the Messenger may be a witness to you. We only established the direction of prayer, which you once followed, that We may distinguish those who follow the Messenger from those who turn on their heels. It is indeed difficult, except for those whom God has guided. But God would never let your faith go to waste. God is Kind towards the people, Merciful.

2:166Those who were followed will then disown those who followed them, and they will see the retribution, and ties between them will be severed.

2:167Those who followed will say, “If only we can have another chance, we will disown them, as they disowned us.” Thus God will show them their deeds, as regrets to them, and they will not come out of the Fire.

2:263Kind words and forgiveness are better than charity followed by insults. God is Rich and Clement.
