The Shaykh : Allah knows best. What the Qur'an indicates is that Allah, Glorified and Exalted is He, speaks the Qur'an, and Jibril receives it from Him, then he descends with it to the Messenger of Allah (peace and blessings be upon him and his family). For this reason, we find in the Qur'an the use of the past tense to describe an event that has already occurred. For example, If Allah had spoken this word before the event took place, it would have been a report of a future matter using a form that indicates completion. The phrase "He has heard" indicates that what was heard has already occurred and that Allah spoke of it after it happened. And many other verses, all of which indicate that Allah spoke the Qur'an at the time of its revelation, because Allah discusses matters that occurred prior to the revelation of the Qur'an. This indicates that Allah speaks it when He wishes to reveal it to Muhammad (peace and blessings be upon him and his family).
