The Grand Imam, Prof. Ahmad At-Tayyeb, said that the Islamic Sharia is a practical law, not isolated from reality. History has proven its success in the applied fields, and its legislation formed the cornerstone of erecting a lofty civilized edifice that stretched into the sky in a short period of time. His Eminence explained that the success of this Sharia was not limited to a specific geographical environment. Rather, as it was destined to succeed in its cradle, it was destined to succeed - and to the same extent - in environments far from it, despite the differences in language, gender, ethnicity, creed, history and civilization. In his Ramadan program Grand Imam At-Tayyeb Talk, the Grand Imam explained that the reason for the ability of Islamic Sharia to lead diverse human societies is that it is a law with fixed obligations in the fields of worship acts, morals and supreme values. These obligations govern social, economic and political life and do not change with the change of people’s lives in general, as they are not subject to the law of human development. On the other hand, the Islamic Sharia has other flexible obligations fit for every field that is subject to civil development, thus changing with its change.

His eminence added that some of the Islamic Sharia provisions are fixed as they are not subject to change; they are the most numerous of the provisions, and the most difficult for mental research. They require mental effort to reach the reason or wisdom of their legislation. The other type of the Sharia provisions is universal, flexible, changing with the movement of development and the law of change; they are few in number and easy to understand. The Grand Imam stressed that this diversity or complementarity in Sharia rulings - constants and variables - came to align the nature of man himself with its diversity and complementarity, as the Islamic law took into account this dual nature in man. It addresses man as a citizen of two different worlds, so it legislated for him detailed, fixed provisions that meet the demands of the ethereal soul, and other few general few provisions that meet the demands of the physical body.
