Respected Dr. Sahib,
I agree with you that the entire Qur'an was revealed at once in one of the nights of Ramadan to the blessed Prophet's heart; it was then relayed to the masses over many years with intervals. As you are awre, the hadith considers Jibreel as some sort of (ma'azallah) Prophet's attendent who used to bring revelation to him every now and then--they say 'according to specific situations'. They also claim that a major portion of the Surah Ahzaab was lost because of the martyrdom of many huffaaz,and that some ahadith were eaten by a goat, etc.
I am sure if I did not read the Qur'an myself and had heard these baseless stories, I would not have even looked at accepting Islam.
