The ruling on the marriage of a brother’s daughters to a woman who breastfed from her brother’s wife
Machine translationRead the Arabic original
The questioner:
Yes, my daughter breastfed from my brother’s wife, and my brother’s daughter breastfed from my wife.
The Shaykh:
She breastfed.
The questioner:
My daughter breastfed from my brother’s wife, and my brother’s daughter breastfed from my wife. Is it permissible for my brother’s other sons to marry my other daughters, and vice versa?
The Shaykh:
If a woman breastfed from her brother’s wife with a lawful breastfeeding of five times or more, then after the breastfeeding she becomes forbidden to his sons and becomes his sister. If she breastfed from your wife five times or more within the two-year period, then none of your children are permissible for him to marry. However, he must marry their sisters who did not breastfeed, who are other sisters. Likewise, if his daughter breastfed from his brother’s wife, she becomes his brother’s daughter, provided the breastfeeding was five times or more within the two-year period; she becomes his brother’s daughter and it is forbidden for his sons to marry her. But there is no harm in his brother’s sons marrying his other daughters. So if she breastfed from his brother’s wife, this should be understood: the one who breastfed from his brother’s wife is not permissible for his sons, and the one who breastfed from your brother’s wife is not permissible for your sons, and the one who breastfed from his brother’s daughters and his wife is not permissible for your sons either. The point is that his brother’s daughter who breastfed from your sons becomes part of your group and is forbidden to your sons, and your daughter who breastfed from his brother’s wife and became part of his brother’s group is not permissible for his sons. As for anyone else, there is no harm.
Yes, my daughter breastfed from my brother’s wife, and my brother’s daughter breastfed from my wife.
The Shaykh:

The questioner:
