Blood transfusion does not take on the ruling of breastfeeding

This is a letter received from Sudan, from Kassa, from Abdul Aziz Muhammad Asht. He says in his letter: Does blood transfusion for a patient bring about any prohibition, such as milk, for example? Please inform us, may Allah reward you.
Answer: No, blood transfusion is not like breastfeeding. Blood transfusion does not cause harm, and its ruling is not the ruling of breastfeeding. So if a husband gives his wife some of his blood to save her life, she does not become forbidden to him because of that. Rather, this is a matter of assistance, like assistance with money.
Breastfeeding is something else; it does not have the ruling of blood, and blood does not have the ruling of breastfeeding. Yes.
The presenter: May Allah reward you.
