Allah revealed Books of guidance through his prophets. Muslims believe in all the Original Books of Allah mentioned in the Qura’n, the Tawrat (Turah of Moses), the Zabur (Psalma of David), the Injeel (Gospel) and Suhuf Ibrahim (the Scrollsof Abraham). The Qur'an is the only book of Allah which exists unchanged in its original form. The other Books are not in their original languages and are distorted and mixed with human words. The Qur'an was recorded as soon as it was revealed and was memorised by heart by Muslims.
