A man married a widow. She has a young daughter. The man she married also has a young son. Is it permissible for this young son to marry this girl or not?
Let it be known that since there is no Mehrem (relationship which prohibits marriage between a male and a female as per Sharia) with a daughter born to a stepmother by her earlier husband, the marriage of the daughter of the woman mentioned in the case to the son of the person mentioned is permissible and correct, and there is no problem in this according to Shar’i law.
كما قال اللہ تعالی : واُحلَّ لکم مّا ورآءکم ذٰلکم أن تبتغوا بأموالکم مّحصنین غیر مصافحین (سورۃ النساء الأیۃ : 24)۔
وفی الفتاوی الھندیۃ : لا بأس بأن يتزوج الرجل امرأة ويتزوج ابنه ابنتها أو أمها، كذا في محيط السرخسي. (القسم الثاني المحرمات بالصهرية ، ج 1، ص 277، ط : دار الفكر، بيروت)۔
