Glorious Quran (English translation and comments)

The Noble Qu'ran (translation with comments and relevant hadith) by Muhsin Khan and Tariq Uddin Al Helali: http://www.mediafire.com/view/?vvoul8qh9tawbxl

I recommend the translation and commentary of Muhsin Khan and Helali the most. Because, it has very authentic translation and explanation using authentic hadith. It is written in easy English and the appendix explains basic terminologies used in Islamic texts.

The other translations are presented below.
