Prayer was imposed by Gabriel, peace be upon him

The answer is: خطأ.

No, prayer was not imposed by Gabriel, peace be upon him. Rather, prayer was imposed in the sky on the night of the Ascension without an intermediary. This event is known as the Night Journey and Mi'raj, when the Prophet ascended to the highest heavens with Gabriel, peace be upon him. It was not imposed on earth, but rather it was imposed in heaven, which indicates its importance, as no intermediary imposed it, but rather God Almighty imposed it. Prayer was imposed on Muslims in Mecca before the Messenger’s migration - may God bless him and grant him peace - from there. So he invited all the messengers from Noah, may God bless him and grant him peace, to the Messenger Muhammad, may God bless him and grant him peace.
