The Calculation of the Waiting Period for a Divorced Woman with Post-Natal Bleeding

Question:
He says: Shaykh, if a woman is divorced while she is experiencing post-natal bleeding, is the purity from the post-natal bleeding considered the first period of purity and counted in the waiting period, or must the woman menstruate and then become pure, and the purity following the first menstruation after the post-natal bleeding is what is counted?

Answer:
As for the waiting period for a divorced woman, if the divorce is final, and if the woman is one who menstruates, her waiting period is three menstrual cycles. The menstrual cycle ends with the complete appearance of purity. So, if the blood stops completely and nothing comes out, and the white discharge appears, or if she tests herself with cotton and nothing appears,
then the menstruation has stopped and ended. She completes three menstrual cycles. As Allah the Exalted said regarding divorced women, they must wait with themselves for three periods. Three periods means three menstrual cycles according to the school of thought. So, when she becomes pure from the last menstrual cycle and sees complete purity, her waiting period ends. It is obligatory for her to perform the full ritual bath and pray. If her blood stops completely in Ramadan before dawn or with the arrival of dawn, it is obligatory for her to fast. Yes.
