This is the place where angels came down to help the Muslims army in the battle. The reason for the name is that the Prophet (PBUH), from the shade, prayed for triumph of Muslims. He repeatedly prayed to God until he honored this nation with a glorious event, never occurred before or after, where angels came down on this mountain. The Almighty Allah says: ([Remember] when you asked help of your Lord, and He answered you, Indeed, I will reinforce you with a thousand from the angels, following one another.(9) And Allah made it not but good tidings and so that your hearts would be assured thereby. And victory is not but from Allah. Indeed, Allah is Exalted in Might and Wise. (10)) Ibn Ishaq said: "The Prophet (PBUH) had shaken while in the shade, then he paid attention and said: This is tiding, Abu Bakr, the triumph of God has come to you. This is Gabriel holding the horse rein riding it, with spots on its curves".
