Does donating blood create the relationship of Mahram?

A: Perhaps the questioner makes an analogy between blood and milk that establishes a relationship of a Mahram (spouse or permanently unmarriageable relative). This analogy is not valid for two reasons:First, blood is not a source of nourishment like milk.Second, breastfeeding that establishes a relationship of a Mahram is based on two conditions: (1) the number of breastfeeding should not be less than five;(2) this should occur within the first two years of the infant's life.Therefore, this blood which you donated to your wife does not have any effect on your marital life.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
