The waiting period of the divorced woman whose menstruation has ceased due to breastfeeding

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the waiting period for a woman who was divorced while she was breastfeeding her son, and whose menstruation has ceased because of the breastfeeding?

Answer:
She waits until the menstruation returns, and she observes the waiting period based on that. The one who observes the waiting period based on months is the postmenopausal woman who does not expect menstruation to return due to her advanced age, or the young girl who has not yet reached the age of menstruation; these observe the waiting period based on months. As for the menstruating woman whose menstruation has stopped, and she knows what caused it to stop, whether it was medication, breastfeeding, or pregnancy, she remains in the waiting period until it returns to her, except for the pregnant woman, whose waiting period is the delivery of the child. Yes.
