Musnad Ahmad 2942
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn ‘Abbas (رضي الله عنه) said: The Prophet (ﷺ) asked Jibreel to appear to him in his real form, and he said: Ask your Lord. So he asked his Lord. Then some shade began to appear from the east, and it began to rise and spread. When the Prophet (ﷺ) saw it, he fainted. Then (Jibreel) came and revived him, and wiped the saliva from his mouth.
