Concept:In Islamic law, different terms describe divorce based on who initiates it and whether it is by mutual consent.
Explanation:The dissolution of marriage by the mutual agreement of the couple is called Mubara'ah.
In Mubara'ah, both husband and wife willingly agree to separate, and neither party is forced to seek the divorce.
Khul' is a divorce initiated by the wife, usually after she gives some compensation to the husband.
Faskh refers to the annulment of a marriage by a qadi or judge due to valid reasons.
Li'an is the oath of condemnation exchanged by spouses when a husband makes an accusation of adultery without witnesses.
