It is the most important duty of a true believer to understand the Qur'an and live by it. A believer has to know the Qur'an very well in order to be guided to the right way, to fulfil the commands of Allah completely, to revere Him properly and to evaluate all issues from the Qur'an's viewpoint. In this index, similar subjects have been grouped together, and the words in the verses have been catalogued alphabetically to help the reader to learn the rulings of the Qur'an on a specific subject and to make research easier. It is hoped that this study also helps those who aim to attain the good pleasure, mercy and Paradise of Allah by learning the Qur'an and living by it.
