What benefit did you gain from your treatment with water for forty days?

The questioner : May Allah have mercy on your parents. Regarding your treatment, which you underwent for only forty days—for the sake of understanding—what benefit did you gain from it?

The Shaykh : I hope our brothers who read the story of my forty-day fast understand that it was a medical fast, not a religious fast. In other words, whenever I felt the need for water, I drank, just as I am drinking now. This is not a religious fast where one abstains from dawn until sunset. No, rather, if we are to be clear in our expression, it was starving the self from everything that enters the stomach except water. This is, of course, a matter of medical treatment, as I had some disturbances in my intestines and treated myself extensively with some doctors there. We would go to them, and they would give us medicine for a week, two weeks, or three. Due to the frequent visits, I would get tired of it and stop, and the illness would remain as it was afterward.
I read some books that discuss starving and treating with hunger. It became clear to me that the matter is as the Prophet (peace and blessings be upon him) indicated in some hadiths: , and there is a hadith that indicates that the stomach is the home of disease; however, from the perspective of hadith, it is not authentic, but from the medical perspective, the meaning is correct.
The important thing is that I entered into this starving, and nothing entered my stomach for forty days except water. And behind that, the treatment was indeed completely clear. This is what happened to me.
Yes.
