The breastfeeding that prohibits marriage takes place only if the baby breastfeeds five times or more during the first two years of breastfeeding. Every time a baby holds the breast and sucks milk and then leaves it to take a breath or to suck the other breast, this is counted as one time of suckling until five times of sucklings are counted. If the number is less than five times, even if they are four times of suckling, this breastfeeding does not prohibit marriage. Mentioning the women prohibited to marry, Allah (Exalted be He) says,
...your foster mothers who gave you suck, your foster milk suckling sisters.
It is reported by Al-Bukhari and Muslim that the Prophet (peace be upon him) said,
Milk relationships are equal to blood relationships in rendering marriage unlawful i.e. whatever is prohibited due to blood relationships is also prohibited by milk relationships.
It is related by
`Aishah (may Allah be pleased with her) said:
Amongst what was sent down of the Qur'an was 'ten known times of suckling (Part No. 21; Page No. 85) forbid marriage'. Then it was abrogated by 'five known times of suckling'. The Messenger of Allah (peace be upon him) died while the latter rule was in force.
Thus, if you were breastfed by your maternal aunt in the manner described above, then she becomes your milk-mother; her husband becomes your milk-father and the other wife of your paternal uncle becomes the wife of your milk-father; her sons and daughters of your paternal uncle become your paternal are your milk-siblings and you become a paternal milk-aunt to the son of your paternal uncle's daughter and a maternal milk-aunt to the children breastfed by your paternal uncle's daughter, since you are her milk-sister. Accordingly, the sons of your paternal uncle of his other wife become unmarriageable to you and to your daughter. As for the (male) children breastfed by your paternal uncle's daughter whom you became her milk sister, they become unmarriageable to you alone, not to your daughter, as you are their maternal milk-aunt. They also become unmarriageable to the (other) wife of your paternal uncle and to her daughters, since she is their milk grandmother and her daughters are their maternal milk aunts.May Allah grant us success. May Allah's Peace and Blessings be upon our Prophet and upon his family and Companions!
