What is the 'iddah (waiting period) for the woman mentioned in the question, and does her 'iddah begin from the date of the last court session or from the date she receives the divorce decree? What is the duration of the 'iddah and its conditions? And is she obligated to observe a waiting period if the husband appeals?

The 'iddah (waiting period) for a divorced woman begins from the moment the husband pronounces the divorce. However, if the divorce is issued by a judge, the 'iddah begins from the time the final divorce decree is issued. The 'iddah concludes after three menstrual cycles for a woman who menstruates, or three months for a woman who does not menstruate, or upon childbirth for a pregnant woman. The husband's absence from his wife does not negate the obligation of the 'iddah, and it is not permissible for a woman observing 'iddah to marry, nor for her to be proposed to, before the 'iddah period has ended. She must also remain in her home.
