Giving Blood to Another Creates No Kinship

Question

If one Muslim gives blood to another Muslim, man or woman, in what way does a relationship arise between the two? That is, if a man’s blood is given to a man, do both become brothers by blood relationship? Or if a man’s blood is given to a woman, do the two become brother and sister? And is nikah between the two permissible?

Answer

Because of this, no relationship arises between them. As they were before, so they will remain.
