2:10In their hearts is sickness, and God has increased their sickness. They will have a painful punishment because of their denial.

2:104O you who believe! Do not say ambiguous words, but say words of respect, and listen. The disbelievers will have a painful torment.

2:174Those who conceal what God revealed in the Book, and exchange it for a small price—those swallow nothing but fire into their bellies. And God will not speak to them on the Day of Resurrection, nor will He purify them, and they will have a painful punishment.

2:178O you who believe! Retaliation for the murdered is ordained upon you: the free for the free, the slave for the slave, the female for the female. But if he is forgiven by his kin, then grant any reasonable demand, and pay with good will. This is a concession from your Lord, and a mercy. But whoever commits aggression after that, a painful torment awaits him.
