The ruling on the fasting of a sick person who takes pills during the day

Question:
May Allah reward you with good and do you well. A brother says to me: I suffer from diabetes and I take certain pills regularly. Is it valid for me to fast while taking the pills if I take them during the day?

Answer:
He does not fast if his intention is to take them during the day; in that case, he does not fast. Yes, he breaks his fast. If he is healed in the future, and his healing is expected in the future, then he must make up the days he broke. As for the saying of Allah the Exalted: As for if this illness is chronic with him and he needs treatment year-round, night and day, and he is unable to fast, neither in its proper time nor by making it up, then it is sufficient for him to feed a poor person for each day the amount of half a sa' of food. He gives it to the poor, whether he collects the days that are due from him and pays them in one lump sum, or pays them separately, and whether he gives it to one person or to several people.
His saying, the Exalted: regarding your children, "food for the poor," means that they are able to bear it, meaning that fasting is difficult for them, and for a chronic illness, or due to old age and decrepitude.
