Kaab bin Malik reported,
The Messenger of Allah ﷺ said, "People will be raised up on the Day of Resurrection, and I, along with my nation, will be upon a hill. My Lord 
will clothe me in a green garment, then I will be granted permission to speak, and I will say whatever Allah wills me to say. That is the praiseworthy station."
Ahmad 15783
