The concession to become a multiple of partial matters of a science of sciences. Therefore, we will limit ourselves in presenting this division to mentioning the basic divisions of science that form the general framework of Ibn Tumart's classification of sciences. Science is divided in principle into three divisions: knowledge of religion, knowledge of the world, and knowledge of what leads to them.

Knowledge of Religion: 1 It is divided into three divisions: knowledge of God, knowledge of the Messenger, and knowledge of what he brought.

Knowledge of God: It is divided into three divisions: -a First: Knowledge of what is obligatory for God Almighty, which is three divisions: Existence. Which is based on the negation of anthropomorphism, which is represented in three forms: change Far from being bound by time, spatial confinement arising from being bound by space, and composition arising Oneness. Which is based on the negation of a partner. Perfection. Which is based on the negation of deficiencies, which are represented in three forms: what prevents and what prevents speech, and what hinders perception, such as blindness and deafness. Actions, such as inability and ignorance. Such as muteness.

These are three matters: affirmation, knowledge of what is impossible for God Almighty. And the partner. And deficiencies.

Third: Knowledge of what is permissible for God. These are three matters: creating the world, and its annihilation without its existence, and its restoration without its annihilation.

Knowledge of the Messenger: It is divided into three divisions: -b First: Knowledge of what is obligatory to affirm for him. These are matters such as truthfulness and trustworthiness. 166
