that she does not need a waiting period to establish that she is not pregnant, he will wait until he has established that she is not pregnant.
His statement: “A pregnant woman’s waiting period to establish that she is not pregnant ends with her delivery”—that is, once she gives birth, it has been established that she is not pregnant. This is correct, even if she gives birth an hour after the purchase. If she remains pregnant for three years, he must wait until she gives birth.
His statement: “As for one who menstruates”—that is, her waiting period to establish that she is not pregnant is “one menstrual period,” because this is not an iddah (legally prescribed waiting period); rather, the purpose is to ascertain that the womb is free of pregnancy. Thus, once she menstruates a single time, she becomes lawful. If her menstruation has ceased and she does not know the reason, she waits ten months: nine months for pregnancy and one month to establish that she is not pregnant.
His statement: “The woman past menopause and the young girl: one month”—that is, the woman past menopause and the young girl establish that they are not pregnant by the passing of one month.
