It is further based on a hadith in which Muhammad instructs a man to agree to his wife's wish of divorce if she gives back a garden received from him as part of her "mahr". A khul' is concluded when the couple agrees to a divorce in exchange for a monetary compensation paid by the wife, which cannot exceed the value of the "mahr" she had received, and is generally a smaller sum or involves forfeiting the still unpaid portion. Hanafis and Malikis do not require a compensation paid by the wife. The divorce is final and irrevocable, effective when the contract is concluded. The couple cannot reconcile during the waiting period, defined as in the case of talaq, but the husband is required to pay maintenance during its term, unless the requirement is waived by the contract. As in the case of "talaq", remarriage is possible until a khul' is concluded for a third time. If the husband pressures his wife to agree to khul' instead of pronouncing talaq, which would let him avoid attendant financial responsibilities, the divorce is considered to be invalid. Like talaq, khulʿ takes place out of court.
