4:18But repentance is not available for those who commit evils, until when death approaches one of them, he says, “Now I repent,” nor for those who die as disbelievers. These—We have prepared for them a painful torment.

4:37Those who are stingy, and exhort people to stinginess, and conceal what God has given them from His bounty. We have prepared for the disbelievers a disgraceful punishment.

4:102When you are among them, and you stand to lead them in prayer, let a group of them stand with you, and let them hold their weapons. Then, when they have done their prostrations, let them withdraw to the rear, and let another group, that have not prayed yet, come forward and pray with you; and let them take their precautions and their weapons. Those who disbelieve would like you to neglect your weapons and your equipment, so they can attack you in a single assault. You commit no error, if you are hampered by rain or are sick, by putting down your weapons; but take precautions. Indeed, God has prepared for the disbelievers a demeaning punishment.

4:151These are the unbelievers, truly. We have prepared for the unbelievers a shameful punishment.

4:161And for their taking usury, although they were forbidden it; and for their consuming people's wealth dishonestly. We have prepared for the faithless among them a painful torment.
