My sister’s daughter was breastfed five times in separate instances, then she was breastfed a fifth time, but she drank only a little and then fell asleep. What is the ruling in Islam regarding this?

Question:
May Allah reward you with good, and may He do you good. A woman from the Kingdom sent a question saying: I breastfed my sister’s daughter four times, separated by several months. Then I breastfed her a fifth time, but I am uncertain about this last feeding. When I breastfed her, the baby took the breast and drank a little, then fell asleep on it. I do not think this feeding satisfied her hunger. What is the ruling in Islam regarding this? Please give us a ruling, and may you be rewarded, with clarification. May Allah reward you with good.

Answer:
The limit of a breastfeed is not, as the questioner understood, that the child be satisfied. Rather, the limit of a breastfeed is that the child sucks the milk, even if it is a small amount. If she sucks it and then leaves it, this counts as a breastfeed, even if the milk she sucked was small. As long as she breastfed this child five times, she becomes her mother through breastfeeding, and the mahram (forbidden relatives) of the wet nurse become the mahram of the breastfed child.
