All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.

Brother, first of all, we’d like to say that we are impressed by your question, which emanates from a thoughtful heart. May Allah Almighty help us all adhere to the principles of this true religion, Islam, and enable us to be among the dwellers of Paradise in the Hereafter. Ameen.

Such studies as you point out, and others, point to the fact that the Prophet (peace and blessings be upon him) is a true Prophet of Allah who delivered the Divine message for the prosperity of mankind.

In his response to your question, Dr. Sano Koutoub Moustapha, professor of Fiqh and Its Principles, International Islamic University, Malaysia, states:

It is so great to hear this scientific conclusion about the effect of fasting on the health. It proves that the Prophet of Islam (peace and blessings be upon him) is a real Messenger of Allah, and he delivered the message of Allah to mankind. However, the rightness of the prophetic statement has been proven long time ago and this scientific conclusion is an additional confirmation to his statement.

Let us strengthen our commitment to this true religion by following its teachings which were meant for the interest of mankind. Thank you for sharing this wonderful information. May Allah bless you.

Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, adds:

If these studies prove that fasting may contribute to better health than simply leading a lifestyle of gluttony, it is simply a truth that humanity has learnt from divine inspiration as well as from their own traditional practices of prevention and health. The Prophet (peace and blessings be upon him) is reported to have said: "Fast frequently in order to gain better health." He is also reported to have said: "The stomach is the warehouse of diseases." Therefore, he ordered the faithful to eat only sparingly: "It is sufficient for human beings to partake a few morsels of food everyday that would maintain his posture. If he must indulge, let him divide his stomach into three parts: one third for his food, one third for water, and the remaining one third for the air passage."

These are wonderful truths that have been tested and proven to be perfect recipes for health, and they undoubtedly confirm the veracity of the Divine Message of the Prophet (peace and blessings be upon him). The Qur'an says: (He (the Prophet) does not speak out of his own whims; rather he is inspired by Allah.)
