Al -Razi's humility and austerity in the course of his life is clear to us from his words in the book "The Philosophical Biography", where he says: "He has no evil on his evil in collecting money and exhorting it, or on people's disputes, their opponents, and their injustice, but rather it is known from me against all of this and the contradiction of many of my rights. As for my condition in my restaurant, my drink, and my love, it may be known to those who see this from me that I did not go to the end of the excess, as well as in all my conditions, which this is watched from clothing, installation, servant, or maid.
