Suckling from a woman makes one the brother of all her children and her husband's children from other wives
a person is suckled five or more times by a woman together with her daughter, does it become unlawful for the brothers of this person to marry the daughters of this woman,
because she suckled their brother and vice versa? In other words, will it become unlawful for the children of the woman either by her husband when she gave milk or by another ex-husband to be married by the full, maternal, or paternal siblings of the suckled person, old or young?Please explain the breastfeeding that prohibits marriage and that which does not in detail.
The breastfeeding that prohibits marriage takes place only if the baby is breastfed 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 (Part No. 21; Page No. 82) until five times of suckling 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)
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 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 a person is suckled by a woman in the manner described above, then he becomes a milk-child to her and her husband and then a brother to all her sons and daughters she bore to her present husband or any other one that she married before or may marry in the future. That is because this baby is the milk-baby of this mother. This baby is also a brother to all sons and daughters of the milk-husband through other wives, since he is the milk-father of the child. As for the siblings of the person who is breastfed, the prohibition is not applied to them, as the ruling is confined to the milk-child who suckled the milk and acquired this relationship due to it.
