The Revelation of the Qur'an: Sometimes the expression is "We revealed to you," and sometimes "upon you." Is there a significance to this?

The questioner : The Qur'an was revealed sometimes with the expression, for example, sometimes and sometimes , meaning "revealed" and "sent down," "to you" and "upon you." Is there a difference between them?
The Shaykh : It is for the sake of variation. For example, "We revealed" is considered in another sense to be the sending down of the whole, meaning He sent it down in its entirety. If this was the last thing to be sent down, it is clear that the Qur'an was completed in its entirety. If it was the last thing to be sent down, it is considered that it will be completed, because when it is all completed, it is as if it was sent down as a single unit, because the whole of it has now been sent down. As for "to you," it indicates the goal, meaning that the end of the revelation is the Messenger. As for "upon you," it indicates elevation and stability. For this reason, He said: , and this is more eloquent than "to you," because when it reaches the point of settling in the heart, it becomes more eloquent.
