Donating blood whilst fasting.

Question: Does donating blood during the day in Ramadhaan break the fast? Response: Yes! If he donates and a lot of blood is drawn out, then he breaks his fast as it is regarded as similar to cupping (hijaamah). Shaykh Ibn Fowzaan Fataawa Ramadhaan – Volume 2, Page 467, Fatwa No.405. fatwaonline.com
