Conditions of suckling which causes to be Mahram

2483. The following are the eight conditions under which suckling child becomes the cause of being Mahram.

 1. That the child sucks the milk of a woman who is alive. It is of no consequence if milk is drawn from the breast of a woman who is dead.
2. That the milk of the woman should not be the product of fornication or adultery. Hence, if the milk for an illegitimate child is breastfed to another child, the 3. latter will not become Mahram of anyone.
4. That the child sucks milk directly from the breasts of the woman. Hence, if milk is poured into its mouth, it has no consequence.
5. That the milk be pure and unadulterated.
 That the milk be of one husband only. Hence, if a breast – feeding woman is divorced and then she marries another man by whom she becomes pregnant, if the milk of the first pregnancy still continues from the breast till she gives birth to the other child, for example, she feeds any child eight times with the milk from her first pregnancy before giving birth, and feeds the same child seven times with the milk from the second pregnancy, after giving birth, that child will not become Mahram of anyone.
6. That the child does not throw up the milk due to illness. If it vomits the milk, as per obligatory precaution, those who become Mahram of that child because of suckling, they should not marry with that child, and should not look at them with the intention of them being his Mahram.

7. That if a child suckles fifteen times or for one full day and night to its full, as will be explained later, or the suckling should be of such quantity that it could be said that the bones of the child were strengthened and the flesh allowed to grow.

8. That the child should not have completed two years of his age, and, if it is suckled after it has completed two years of its age, it does not become Mahram of anyone. In fact, if, for example, it sucks milk fourteen times before completing its two years, and once after completing its two years, it does not become Mahram of anyone.
But, if milk continues from the breast for more than two years since a woman gave birth to her child, and she suckles the child continuously, that child, as per obligatory precaution, will become Mahram of those who have been mentioned above. However, as per precautionary measures, they should not look at the child with the intention of them being its Mahram.

2484. It is necessary that the suckling child should not have taken any other food, or sucked milk from any other person, during one full day and night. However, if it takes very little food, so little that one may not say that it has taken any food in between, there is no harm in it.
Also, it should have suckled the milk of only one woman fifteen times, and during these fifteen times, it should not have sucked the milk of any other woman. And it should have sucked milk every time without a gap, however, if while suckling milk it pauses to breathe, or waits a little, in a manner that from the time it started till the end, it is taken as one suckling, there is no objection.

2485. If a woman suckles a child from the milk of her husband, and when she later marries another man, suckles another child from the milk of her second husband, those two children do not become Mahram of each other, although it is better that they do not marry each other.
