Is ending the marriage in return for compensation from the wife considered divorce or an annulment? In the event of separation after agreeing on compensation from the wife, regardless of the wording used, the marriage contract will be deemed annulled, and the case will not be treated like a divorce. This ruling is one of the views of the Hanbali Madhabs and the view of a group of righteous predecessors. It is also the view of Ibn Taymiyyah, al-Shawkaanee, and Ibn ‘Uthaymeen. 
2. The difference between divorce and annulment: Ending the marriage can be via divorce or marriage annulment, which are different from each other as follows:
a. Divorce is a right that can be exercised by the husband, which he issues willingly and by choice using the words of divorce, while annulment is not the same.
b. The annulment of marriage is irrevocable, and once it is established, the man can have the woman back only by conducting a new marriage contract with a new bride price and after her consent. However, divorce in some instances can be revocable, and the husband can take back his wife during her waiting period without her consent.
c. Annulment before consummating the marriage does not entitle the woman to anything from her bride price, whereas in the case of divorce, after consummating the marriage and after specifying the bride price, the woman is entitled to half of the agreed-on bride price.
d. An annulment does not count in the three times of divorce that the man can use.
e. Divorce does not require the rule of court or the consent of the wife, while marriage annulment requires that.
f. An annulment can only be established due to a valid reason, such as a defect, while divorce may take place due to a reason or without reason.
3. Khul’ serves as a revocable divorce: The four Madhabs agree that Khul is deemed as a revocable divorce.
