i wanted to ask "is there a hadith admonishing to not eat until being hungry?" and i have found this question in "similar questions" block. the answer to that question is enough for me.
i wanted to quote a text in my question. since i prepared to write my question, translated the text, using google, i make a new question, though i am not very interested to know out answer to it.
in book "kitab at-tarbiya" in tatar language, qayum nasiri writes:
TWENTY-FIRST UPBRINGING One of the kings of Gajam sent a skilled doctor to the service of the Prophet (peace and blessings of Allaah be upon him). He lived in Arab countries for many years. No one came up to him, saying, "Heal me." One day he came to the Prophet (peace and blessings of Allaah be upon him) and complained. "I've been here for days, and no one has paid attention to me," he said. The Prophet (peace and blessings of Allaah be upon him) said: “The custom of this people is that they will not eat anything until they want to eat it, and they will start to refuse from food before they are full, that is, they will not eat until they are satiated.” The doctor said, "If that's the way to heal," then kissed the ground and left. Now, son, has this story sufficed for your upbringing? Don't eat your stomach full, you'll be in health, be satisfied with little.
the russian version of it says this way:
It is known that one of the Persian kings once sent his best healer to Arabia to serve the prophet.
do you know what is source of this story?
i read this book in paper form in past. now, i used https://nsportal.ru/shkola/rodnoy-yazyk-i-literatura/library/2020/02/02/k-nasyyri-trbiya-kitaby where is also russian translation of it.
