Q: Allah (Glorified be He) willed that I have been suffering from diabetes since I was about 14 years old (Part No. 9; Page No. 100) and in 17 Muharram, 1411 A.H., I had kidney failure; and in 16 Jumada Al-Thany, 1412 A.H., I had a kidney transplant in the Arab Republic of Egypt, which cost me a large sum of money. When Ramadan, 1412 A.H. started, the doctor ordered me not to fast, so I fed one Miskin (needy) for each day. And, I have a follow-up in hospital every month and a half, so I asked the doctor about Sawm, and he told me to fast if I can, and not to fast if I am not able to, knowing that the doctor is a Muslim, and he is Sudanese.Knowing, respected Shaykh, that the doctor told me that: If you fast, do not do a lot of work and do not sleep at night so as to make up for the liquids that you lost throughout the day. In addition, I take medicine for diabetes in the morning and in the evening, and another medicine between 9:00 am and 10:00 am, and between 9:00 pm and 10:00 pm. The doctor has also advised me to drink 4 or at least 3 bottles of mineral water a day. Knowing that I argued with the doctor about Sawm and he did not tell me whether to fast or not, I ask Allah (Exalted be He), then Your Eminence, to answer my question and tell me whether I can fast or not. May Allah reward you with the best.
