Q: My present wife's ex-husband has a daughter with another woman. Is it permissible for me to marry this man's daughter at the same time as being married to my wife?

A: It is permissible for you to be married to both your present wife (Part No. 18; Page No. 355) and your wife’s ex-husband’s daughter from another woman, as Allah (Exalted be He) does not declare that marriage to the two of them at the same time is Haram (prohibited) in the context of mentioning the women a man is forbidden from marrying, neither did the Prophet (peace be upon him). After mentioning the women that a man is forbidden from marrying, Allah (Exalted be He) says: All others are lawful Therefore, being married to them both comes under the general ruling of this statement, as a man is forbidden from marrying a woman and any of her close relatives at the same time due to fear of severing close ties of kinship, and there is no close relationship between these two women. ‘Abdullah ibn Ja‘far did this, as did Safwan ibn Umayyah, and no one is known to have objected to them doing so. May Allah grant us success. May peace and blessings be upon our Prophet, his family, and Companions.
