You mentioned in a previous question that there is no issue in donating blood, rather it could become obligatory in order to preserve the life of one whose life is respected [li Hifth al-nafs al-muhtaramah]. Does the aforementioned permissibility include both believers as well as disbelievers [kuffar]? I ask because the answer did not mention any details with regards to applicability to disbelievers or Muslims (in general) or Shiites (specifically), while simultaneously there is a decree [fatwa] on the website of IslamAsil which forbids donating blood to disbelievers and Nawasib [those who have adopted enmity towards Ahl al-Bayt (as)].
