this is the worst assumption anyone could have, The Prophet (SAAW) was here to deliver the message of Allah all Mighty for whole world AND that suppose to last till the hour is establish… Knowing this only mis-guided will assume that the Prophet (SAAW) left Quran without compilation… the Sahaba (RZA) only gave it down in the order It was compiled by the Messenger of Allah All Mighty, the order of Ayaat in any Sura, the order of all Sura has been compiled by none other but the Prophet (SAAW).. It make absoultely no sense that a Person is assgined a duty and he leaves the work half done… untill and unless some body want to make room out of it…
No comments on your bughaz-e-Sahaba.. a man who doubt the Student actually is capabilities of the Teacher (SAAW)…
