Blood donation should be avoided during the day of fasting because taking a large amount of blood from a fasting person to donate it to a person who needs it, has the same effect on the body as cupping, which risks the status of the fast, according to many scholars.

Based on this, if the fast is obligatory, then it is not permissible for anyone to donate a large amount of blood to anyone unless the person who is to receive that blood is in dire need and cannot wait until after the sun sets, and the doctors have decided that the blood of this fasting person will benefit him and will meet his immediate need for it. In this case, the person who will donate the blood can break his fast to donate a large amount of blood and can eat and drink to regain his strength, and he should make up this day after Ramadan ends.
