Which of the following is not a form of divorce under Muslim Law ?

The correct answer is (b), Talak-ul-bidda.

Talak-ul-bidda is a form of divorce that is not allowed under Muslim law. It is a type of divorce that is pronounced in three consecutive utterances, without any intervening period of reconciliation. This type of divorce is considered to be unfair to the wife, as it does not give her any opportunity to try to save her marriage.

The other options, Hasan Talak, Idda, and Khula, are all forms of divorce that are allowed under Muslim law.

• Hasan Talak is a type of divorce that is pronounced in one utterance. It is considered to be the most lenient form of divorce, as it gives the wife the opportunity to try to save her marriage.
• Idda is the period of time that a woman must wait after a divorce before she can remarry. This period is usually three months, but it can be longer or shorter depending on the circumstances.
• Khula is a type of divorce that is initiated by the wife. It is a form of divorce that is allowed under Muslim law, but it is not always easy to obtain. The husband must agree to the divorce, and he may be required to pay the wife a sum of money in compensation.
