Can I donate blood while fasting?
Yes, according to most scholars, donating blood does not break your fast. But giving a full unit of blood can make you weak, and blood services usually ask you to eat and drink before and after. Many people find it easier to donate after iftar.
What scholars say
The question goes back to cupping (hijamah), where blood is drawn from the body. The Prophet ﷺ had cupping while he was fasting (Sahih al-Bukhari 1939). The Companion Anas was asked whether they disliked cupping for a fasting person, and he said no, only if it made the person weak (Sahih al-Bukhari 1940).
Based on this, the Hanafi, Maliki and Shafi'i schools say losing blood does not break the fast. The Hanbali school holds that cupping does break it, based on the hadith "The one who cups and the one who is cupped have broken their fast" (Sunan Abi Dawud 2367), and some Hanbali scholars apply this to large blood donations too. Most others see that hadith as earlier and later replaced, or as a warning about weakness.
Small amounts of blood
- Blood tests: don't break the fast, according to all four schools.
- Finger-prick tests for diabetes: fine.
- Nosebleeds, cuts or a dentist visit: don't break the fast, as long as you don't swallow the blood.
The practical side
Blood services like the NHS in the UK and the Red Cross in the USA tell donors to eat a meal and drink plenty of fluids before donating, and to drink straight afterwards. Fainting or dizziness is more likely on an empty stomach. If you donate during the day, you can't do that. So the best option is to book a slot in the evening, after iftar. Many mosques and Muslim charities also run blood drives in Ramadan in the evening for exactly this reason.
If you do donate in the day and feel faint, you may break your fast and make the day up later. Your health is not something to gamble with. For what to eat at sunset, see What is iftar and how do I break my fast?
A beautiful act of charity
Saving a life is hugely rewarded in Islam, and many scholars encourage blood donation as a form of sadaqah. Organ donation is a related, longer discussion. See Can I donate my organs as a Muslim?
