When gibrael first time talked with The Prophet Muhammad then
The Prophet (ﷺ) fled from the cave, and when he was halfway down the slope of the mountain he heard a voice above him saying: “O Muhammad, thou art the Messenger of God, and I am Jibraeel (Gabriel)”. The Prophet (ﷺ) stood gazing at the angel; then he turned away from him, but whichever way he looked the angel was always there on the horizon, whether it was to the north, east, south or west. Finally the angel turned away. The Prophet (ﷺ) was terrified and his heart was pounding hard. He returned home to Khadija (رضي الله عنها) and said, “Cover me!”. Khadija (رضي الله عنها) covered him and helped him calm down.
