I suffer from renal failure which necessitates undergoing dialysis three times a week. Blood is pumped through a device that filters waste from the blood and replaces lost minerals and vitamins. Please note that the procedure is performed via arteries and veins. My question is whether dialysis invalidates fasting or must only be performed after I break my fast.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Dialysis does not invalidate fasting.
Answering your question, Dar Al-Ifta Al-Misriyyah, states:
There is no harm in undergoing dialysis while fasting provided the procedure is performed via veins and arteries. Based on this, dialysis does not invalidate fasting.
Almighty Allah knows best.
