To Wed Sister-in-law
Issue No. 2046- If a man marries a woman (whether the marriage is permanent or temporary), he cannot marry his wife’s sister, as long as she is his wife. Even after divorce, as long as she is in ‘iddah (the waiting period), if it is the ‘iddah for rij‘ī divorce (revocable divorce) (details of which will be explained under the rulings relating to 'Divorce'), and as a recommended precaution, it would be better that he does not marry her in the ‘iddah of the bā’in divorce (irrevocable divorce) [1] , and also in the waiting period of the temporary marriage, whether it is after the termination of the temporary marriage or after he has forgone its remaining time.
