My mother breastfed my aunt, but she does not know the number of breastfeedings. Does my aunt become our sister?

The questioner:
May Allah reward you. This questioner is asking about breastfeeding. She says: Honorable Shaykh, my mother breastfed my aunt, but my mother did not mention the number of breastfeedings. Knowing that my mother says she feels a heat in her chest when she tells us the story of the breastfeeding. The question is: Does my aunt become our sister or not? If the breastfeeding reaches five suckles.

The Shaykh:
Then she becomes your sister; your aunt becomes your sister. So if her breastfeeding was a great deal, and it is most likely in her mind that it was five breastfeedings or more, then she becomes your sister through breastfeeding. The Messenger of Allah (peace and blessings be upon him) said: . And in the hadith of , the meaning of a breastfeed is a suckle of milk, then he returns to it a second time and suckles. If he completes five suckles of milk, he becomes the son of the wet nurse and the brother of her children. Yes.

The presenter:
So, Shaykh, the rulings related to breastfeeding.

The Shaykh:
We say, how much, Shaykh? Breastfeeding establishes only the prohibition of marriage.

The presenter:
Yes

The Shaykh:
It establishes only the prohibition of marriage, and it does not establish inheritance or guardianship. That is specific to blood relations.
