The Ruling on Qadhf (Slander)
It is impermissible for a Muslim to make a false accusation against his brother, and it is a major sin. It is obligatory to repent from it, and it is also necessary to seek forgiveness from the person against whom the accusation was made. If he does not forgive, then he has the right, under the Sharia, to demand his right.
