It's kind of confusing, but the first verses of quran (iqra' bismi rabbik allathee khalaq) was revealed on this night. As for "the whole quran", I don't know. Mo's homeboy Jibreel revised the entire Quran (that had been revealed to that point) every Ramadan. But then during Mo's last Ramadamdam he revised it twice, so he knew his end was near. Totally awesome.
Not to mention that guy who would scribe for Mo but when the scribe suggested another word/phrase than what was revealed to Mo and Mo agreed to it, the scribe apostasised and miraculously ALLAN revealed a verse condemning people who make false accusations against Mo for inserting something in the KURRY-AN that was not divinely revealed to him.
MOOOO! The world has judged you too harshly my friend. You were misunderstood all along!
