What Is The Textual Basis Of Marriage Prohibition Due To Milk Kinship? What Are The Conditions Of Establishment Of Milk Kinship?

What is the textual basis of marriage prohibition due to milk kinship? What are the conditions of establishment of milk kinship?

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).

According to the majority of fiqh scholars, the milk sucked by a child in the first two years, less or more, is enough to establish a milk kinship. Accordingly, it is not permissible for a girl and boy who sucked milk from the same woman even once up to the age of two to marry each other (Sarakhsi, al-Mabsut, V, 137; Kasani, Bada’i, IV, 8).

On the other hand, Shafiʽis and Hanbalis are of the opinion that in order for the milk kinship to be established, a child who is younger than two years old must be breastfed until the baby is full at five separate times (Ibn Qudamah, al-Mughni, XI, 309; Shirbini, Mughni al-Muhtaj, III, 546).
