(Fatwa: 864/823/B=8/1438)
If in case of keeping fast one fears his life or increase of illness then in such cases it is allowable not to keep the fast of Ramadan. In future when your health is recovered you should make qaza of these fasts. In case your health is not restored then make a will to pay the fidyah of your missed fasts or pay the fidyah in your life time. The fidyah of one fast is 1 kg and 633 gram wheat or its price it should be given to the poor and needy ones.
Allah knows Best!
