Accusations is mentioned in the Quran in these verses:
[12:77] They said, “If he stole, so did a brother of his in the past.” Joseph concealed his feelings in himself, and did not give them any clue. He said (to himself), “You are really bad. God is fully aware of your accusations.”
[24:11] A gang among you produced a big lie. Do not think that it was bad for you; instead, it was good for you. Meanwhile, each one of them has earned his share of the guilt. As for the one who initiated the whole incident, he has incurred a terrible retribution.
[24:12] When you heard it, the believing men and the believing women should have had better thoughts about themselves, and should have said, “This is obviously a big lie.”
[24:13] Only if they produced four witnesses (you may believe them). If they fail to produce the witnesses, then they are, according to God, liars.
[24:14] If it were not for God’s grace towards you, and His mercy in this world and in the Hereafter, you would have suffered a great retribution because of this incident.
[24:15] You fabricated it with your own tongues, and the rest of you repeated it with your mouths without proof. You thought it was simple, when it was, according to God, gross.
[24:16] When you heard it, you should have said, “We will not repeat this. Glory be to You. This is a gross falsehood.”
[24:17] God admonishes you that you shall never do it again, if you are believers.
[24:18] God thus explains the revelations for you. God is Omniscient, Wise.
[24:23] Surely, those who falsely accuse married women who are pious believers have incurred condemnation in this life and in the Hereafter; they have incurred a horrendous retribution.
[24:24] The day will come when their own tongues, hands, and feet will bear witness to everything they had done.
[24:25] On that day, God will requite them fully for their works, and they will find out that God is the Truth.
[24:26] The bad women for the bad men, and the bad men for the bad women, and the good women for the good men, and the good men for the good women. The latter are innocent of such accusations. They have attained forgiveness and a generous reward.
