The form of education which is stored in the cells of brain and which is useless after the death of brain, having no benefit for spiritual maturity is called worldly education.
The education which helps humans to live peacefully and healthily and to gain Paradise is called spiritual education.
The basic source of spiritual education is the True Religion, its teacher is the Prophet, and its curriculum is the Divine Book.
Other belief systems apart from this, which are not based on the True Religion and the Divine Book, whether they are called religions or not, are null and void. They are worthless in the eyes of Allah.
Beginning from ancient times, every age has had its own perverted beliefs that are opposed to the True Religion. The adherents of these perverted beliefs have terrorized the countries in which they dominated, and coerced their people to accept their perverted beliefs.
In fact, the struggle between right and wrong, which began with Adam and Satan, still continues globally. If this is so, how do humans reach the True Religion by overcoming perverted beliefs?
As harmful and edible plants are mixed together in the grasslands, it is natural that right and wrong are mixed together in this world, as it is the testing ground for the Hereafter.
While the animals, which have no reason, avoid harmful plants and eat edible ones, it is the duty of humans who have been embellished with mind and who are candidates for the Paradise, to overcome perverted beliefs and find the True Religion for their future.
