The ruling on the fasting of a kidney transplant patient and of one who dies with fasting days owed

The questioner : The questioner says: I would like to inform you that I underwent a kidney transplant at the beginning of the seventh month of this year. The doctors have advised me against fasting this year. What is obligatory for me to do in this blessed month? I ask for your guidance. Also, what is the ruling on one who dies with fasting days owed for one year or two years, and who was ill?

The Shaykh : As for the questioner who had a kidney transplant and whose doctors told him not to fast, we say: do not fast, do not fast.

Yes. As for one who dies with fasting days owed, if he broke his fast due to his inability and that inability continued until he died, and he knew that it was an illness that would not be cured, then one feeds on his behalf one poor person for every day. The amount of food is approximately one kilogram of rice for each poor person. Oh my Lord.
This one says: If we assume that this man was able to make up the fast but he neglected it, we say that the Prophet (peace and blessings be upon him) said: So if his guardian, meaning his heir, fasts on his behalf, that is good. And if he does not fast, there is no sin on him, but he must feed one poor person for every day he left, according to the number of days he missed.
