May Someone Marry His Brother’s Milk Sibling?

May someone marry his brother’s milk sibling?

Since milk kinship is established only through lactation of a baby by a wet nurse and it is limited to the milk-mother, some of her relatives, the person who was lactated by the said milk-mother, and the biological children of the person who was lactated by the said milk-mother, there is no impediment to marriage between the relatives except these (Mawsili, al-Ikhtiyar, III, 130). Therefore a person may get married to his brother’s milk-sister.
