Explanation of the Hadith: What is forbidden through breastfeeding is forbidden through blood relations

Question:
Honorable Shaykh, this sister, the questioner Umm Salih, says: "What is forbidden through breastfeeding is forbidden through blood relations." What does that mean, with examples?

Answer:
This is the saying of the Messenger (peace and blessings be upon him) . The one who is breastfed is forbidden to the one who breastfed him, and her daughters are forbidden to him because they are his sisters through breastfeeding. His aunts and maternal aunts through breastfeeding are forbidden to him through breastfeeding, just as those are forbidden through blood relations. So his sister through breastfeeding is like his sister through blood relations, his aunt through breastfeeding is like his aunt through blood relations, and his mother through breastfeeding is like his mother through blood relations in terms of being forbidden to him. However, breastfeeding has a specific condition: one or two sucklings do not make it forbidden. Five known sucklings make it forbidden. So it is necessary to have five sucklings, meaning five times he sucks the breast, milk comes down to him, and he swallows it, then he sucks it again until he completes five. Yes.
