The greatest achievement of Islam is that it has freed man from the worship of other beings and delivered him to the worship of the creator of all beings. As a religious text, the Qur'aan is not a record of inventions or discoveries in this life, but rather a revealed book that helps in the replenishment, enlightenment and solace of humanity. Through it, man can help in the development and civilization of this earth, and through it man can ponder the signs of Allaah's creation.
Accordingly, Muslims have concentrated on the study of this universe and made great strides in the fields of medicine, astronomy, mathematics, physics, etc. However, the specifics of these contributions are not the area of concentration for Muslim scholars, and there are perhaps better sources than this forum to explain the role of Muslim scientists, such as books written for this specific purpose. One can always refer to books written by fair-minded non-Muslims about the achievements of al-Khawarizmi in mathematics, Ibn Haytham in physics, al-Idrisi in geography,and Ibn Nafees in the circulatory system.etc.
