May Someone Marry His Milk Father’s Child Born By Another Wife Of The Said Milk Father?

May someone marry his milk father’s child born by another wife of the said milk father?

Marrying milk mother and milk-siblings are prohibited in the Holy Qur’an (Nisa, 4/23). Prophet Muhammad (saw) said, “Those with whom matrimony is haram due to bloodline are also haram due to milk kinship” (Bukhari, Shahadah, 7; Muslim, Rada, 1, 9; Abu Dawud, Nikah, 6). Therefore, just like a person may not marry his sibling that is born from his own father, he also may not marry his milk father’s daughters who were given birth by milk father’s another wife as they will also be milk sisters due to having milk kinship with their father (Sarakhsi, al-Mabsut, V, 242).
