My brother! Two good questions, and before I dive in, let me first apologise to many who have been sending me questions via social media platforms (especially Facebook and X) and have not received a reply. The reason is simple: I have limited time to answer dozens of messages online, since I usually respond to most during my weekly lessons and Tafseer sessions, which I consider more formal and what I can properly manage. I sincerely apologise to all those I have been unable to reply to, in the past, and even in the future. Now, to your first question: selling your blood: this is impermissible by the consensus of all leading Islamic scholars. The Prophet (PBUH) forbade taking payment for blood (see Sahihul Bukhari, Hadith no. 5962). The hadith refers to money earned by selling blood). For further detail, see the book of Lajnatut Da’imah ( Volume 13, Number 71). However, donating blood for free, under medical advice and to save a life, is highly commendable, and encouraged for anyone, regardless of his tribe, race, religion or group (see Qur’an, Suratul An’am, Verse 160). Second question: Selling organs is also prohibited, since your body is a trust from your Creator, Allah. For details, refer to the fatwa of Al-Muntaqa issued by His Eminence, Shaykh Saleh al-Fawzan. That said, donating an organ to save a life is permissible, but with conditions. The conditions are: it must be an organ on which life does not completely depend on (e.g., a kidney or blood vessel). On the contrary, if it’s vital, like heart, liver or brain, then it is not allowed to donate it, except for someone who has been declared medically dead. (see the Resolution No. 2117 of the Islamic Fiqh Council). In summary, selling blood or organs is prohibited; giving them away to save a human life is permissible, as long as the donor’s own life does not depend on that organ. Indeed, Allah is the All-Knowing.
