menstruation. If we say that the menstrual cycle is menstruation, and the period of purity is fifteen days, then the minimum time in which the waiting period expires is thirty-three days and a moment, adding four days to the two periods of purity. If we say that the menstrual cycles are periods of purity, and the minimum period of purity is thirteen days, then her waiting period expires in twenty-eight days and two moments; this occurs if he divorces her at the very last moment of her purity, so she counts it as one cycle, then she counts two other cycles as twenty-six days, with two menstruations between them lasting two days. Thus, when she enters the third menstruation for a moment, her waiting period has expired.

Whenever she claims the expiration of her waiting period by means of menstrual cycles in less than this, her statement is not accepted by anyone to my knowledge, because it does not allow for her truthfulness. If she claims the expiration of her waiting period in less than a month, her statement is not accepted unless with evidence, because Shurayh said: "If she claims that she menstruated three times in a month, and she brings evidence from upright women among her own relatives, whose truthfulness and integrity are approved, that she witnessed the menstrual blood which prohibits her from prayer, and she performs the ritual bath at each cycle and prays, then her waiting period has expired; otherwise, she is a liar." Ali ibn Abi Talib, may Allah be pleased with him, said to him: "Qalun." Its meaning in the Roman (Byzantine) language is: "You have hit the mark" or "You have done well." Thus, Ahmad adopted the statement of Ali regarding the month. If she claims that in more than a month,
