Ruling on blood transfusion between spouses and from a disbeliever to a Muslim

Question:
The presenter, Mu'asir Salim Jar al-Nabi al-Maliki, says in his message: Is it permissible to transfer blood from a husband to his wife, and is it transferred from one person to another even if their religions differ, such as from a Muslim to a communist or from a communist to a Muslim?

Answer:
I see no harm in transferring blood if there is a pressing need for it, if the doctors determine the need for it and this person's blood is compatible with that person's, then there is nothing wrong with it, whether it is from a wife to her husband or from a husband to his wife, or from a disbeliever to a Muslim or from a Muslim to a disbeliever, there is nothing wrong with this, except if the disbeliever is a harbi (enemy combatant) whom the Shari'ah calls for fighting, then nothing is transferred to him, but if the disbeliever is a dhimmi (a non-Muslim under Muslim protection), a mu'ahid (one with a treaty), or a musta'min (a non-Muslim granted safe conduct), then there is no harm.
So the conclusion is: that blood transfusion does not have the effect of breastfeeding. Breastfeeding, if its conditions are met, has an effect and results in prohibition, but blood transfusion does not, it is not like breastfeeding, so there is nothing wrong with transferring blood from a husband to his wife and from a wife to her husband. Yes.
