Is a man permitted to marry the sister of a woman with whom he has committed Zina (unlawful sexual intercourse)?

Primary text

A man who has committed Zina with a woman is forbidden from marrying her sister until her waiting period ends. The ruling for the waiting period following Zina or semen resulting from a شبهة (dubious relationship) is the same as the waiting period following a valid marriage contract. Imam Ahmad stated that if a man commits Zina with a woman, he must refrain from intercourse with his existing wife until she has experienced three menstrual cycles. It is also related from him that the woman with whom Zina occurred must be examined for purity through one menstrual cycle, because the act is without a valid marriage contract, and its consequences do not carry the rulings of marriage.
