Read The Quran Online
Muslims believe that the Prophet Muhammad was the final Messenger of Allah (God) to humanity, and therefore the Quran is the last Message which Allah has sent to us. Its predecessors such as the Torah, Psalms, and Gospels have all been superceded. It is an obligation - and blessing - for all who hear of the Qur'an and Islam to investigate it and evaluate it for themselves. On this site, there are three English translations of the Quran by Yusuf Ali, Pickthal & Shakir.

The Amazing Qur'an
Calling the Qur'an amazing is not something done only by Muslims, who have an appreciation for the book and who are pleased with it; it has been labeled amazing by non-Muslims as well.
