This is my first post in this wonderful site and I thought it would be best that I start my post with the Holy Koran which is available online.  I consider this unique because you will be able to read the Arabic and 3 most prominent transliterations of the verse at the same time.

Because of this comparative feature it gives you a better understanding of the actual verse.  Remember, though the Quran is unique and free from any errors, Transliterations are not.  I therefore suggest one needs to read any Transliteration with the thought that one is reading the meaning of the verse which has been translated by a human being.
