Also asked as: “Can Muslims donate blood?” · “Is giving blood haram?”
Blood donation is permitted by the vast majority of contemporary scholars and Islamic bodies. Many mosques in the UK host blood donation sessions, especially during Ramadan evenings and after Muharram.
Donating while fasting is best done after iftar, as it can weaken you; scholars differ on whether it breaks the fast.
