Revelation Order of the Qur'an. Currently the Quran is Organized in 2 Ways.

1. The Longest Surah (also spelt Soorah) at the Start & the Shortest Surah at the End of the Quran Majeed.

2. And also the Quran is devided into 30 Pars (JUZ), roughly equal size. This is how the Quran is recitated in Ramadan. This is for ease of Remembrance & Recitation.

But the actual order (The Traditional) in which the Quran was revealed is Different. The first verses to be revealed, according to the most correct opinion of scholars, are the first five verses of Surat Al-Alaq, which happens to be Surah 96 of the 114 chapters of the Quran.

It is best to read the Quraan in the way it is set, the Quran is compiled with the precise knowledge of Allah and His Messenger (saws), and it is arranged with Surah 001 - Al-Fatiha (The Opening) at the Start andSurah 114 - An-Nas (The Mankind) at the end. Allah Subhanah Himself declares in His Glorious Quran that it is upto Him to reveal the Quran, upto Him to compile the Quran, and upto to Him to guard it against any corruption whatsoever.

But there is no harm in reading it in the revelation order.

The Chronological order is as Follows.
