False accusation is worse than backbiting. It is to falsely attribute a deficiency or an offence to a believing person. It is certain that this transgression is the most wicked of attacks upon the prestige of a believer.

1. Allah the Most High said: “And whoever commits a fault or a sin, then accuses of it one innocent, he indeed takes upon himself the burden of a calumny and a manifest sin.”
2. He also said: “Surely (as for) those who speak evilof Allah and His Apostle, Allah has cursed them in this world and the hereafter, and He has prepared for them a chastisement bringing disgrace.”
3. The Holy Prophet Muhammad (s.a.w.a.) said:“Backbiting is speaking about your brother what he does not like to be mentioned.” And he added: “Know that if you mention what is actually in him, this is backbiting; and if you mention what is not actually in him, this is a false accusation.”
4. Imam Ja’far al-Sadiq (a.s.) said: “Backbiting issaying about your brother what Allah has hidden for him. But mentioning what is not hidden, for example, a coarse personality or hastiness, which is open characteristics, is not backbiting. However false accusation is mentioning negative qualities that are not in him.”
5. He (a.s.) also said: “Anyone who falsely accuses abeliever, male or female, of what is not in him on the Day he will be raised he will remain in ‘tinat khabal’ until he is released from it.” Someone asked: “What is tinat khabal?” He (a.s.) said: “It is a kind of pus that is secreted from the sexual organs of prostitutes.”
6. He (a.s.) also said: “Anyone who falsely accuses abeliever Allah will imprison him in the pus from the sexual organs of prostitutes, until he is released from what he said.” He also added: “Backbiting is saying about your brother what Allah had hidden for him; but if you say what is not in him, then it is what Allah said in His Book: ‘He indeed takes upon himself the burden of a calumny and a manifest sin.'[19]”
