My sister in law (sali/wife’s sister) is widow; I like to do nikah with her. Is this possible? My wife is living with me. Please, advise in this matter.
بسم الله الرحمن الرحيم
(Fatwa: 1107/846/D=9/1434)
It is unlawful to marry sali (wife’s sister) while wife is in nikah. Combining two sisters in nikah is forbidden by the Quran.
Allah knows Best!
