3:21As for those who defy God’s revelations, and kill the prophets unjustly, and kill those who advocate justice among the people—promise them a painful retribution.

3:77Those who exchange the covenant of God, and their vows, for a small price, will have no share in the Hereafter, and God will not speak to them, nor will He look at them on the Day of Resurrection, nor will He purify them. They will have a painful punishment.

3:91As for those who disbelieve and die disbelievers, even the earth full of gold would not be accepted from any of them, were he to offer it for ransom. These will have a painful torment, and will have no saviors.

3:177Those who exchange blasphemy for faith will not harm God in the least. A painful torment awaits them.

3:188Do not think that those who rejoice in what they have done, and love to be praised for what they have not done—do not think they can evade the punishment. They will have a painful punishment.
