“I once provided transportation for Abu ‘Abd Allah (a.s.), from al-Medina to Mecca. When we arrived at Masjid of al-Ghadir Khumm, he looked to the left side of the Masjid and said this. ‘That is the place where the Messenger of Allah (saww) set foot when he (the Messenger of Allah) said, “On whoever I have Divine Authority, Ali also has Divine Authority.” He then looked to the other side and said, ‘That is the place for the tent of abu so and so and Salim mawla Abu Hudhayfah and Abu ‘Ubayda al-Jarrah, who on seeing him raising his hands, said to each other, “Look at his eyes turning like the eyes of an insane person.” Jibril at this time came with this verse of the Holy Quran, {The disbelievers almost make you slip up, by their piercing eyes when they hear (passages) of the Quran and say that he is an insane person. It (Quran) is not anything other than good advice from the Lord of the worlds.} (54:50 - 51) ”
