Answered by Ustadh Salman Younas
Question: I am thinking of donating blood but before making any appointments I want to know if it is permissible?
Answer: assalamu alaykum
It would be permissible for you to donate blood to institutes like blood banks that utilize it for cases of medical need and necessity as long as it is safe for you to do so.
Although the default ruling is that blood transfusions are not permitted because blood is (a) part of the human body and (b) filthy, classical jurists made an exception when there was genuine need. [Fatawa al-Hindiya (5:355)]
