Maliks Muwatta Book 20, Hadith Number 254.
Section : The Hajj in General.
Yahya related to me from Malik from Ibrahim ibn Abi Abla from Talha ibn Ubaydullah ibn Kariyz that the Messenger of Allah, may Allah bless him and grant him peace, said, “Shaytan is not considered more abased or more cast out or more contemptible or more angry on any day than on the Day of Arafa. That is only because he sees the descent of the Mercy and Allah’s disregard for great wrong actions. That is except from what he was shown on the Day of Badr.” Someone said, “What was he shown on the Day of Badr, Messenger of Allah?” He said, “Didn’t he see Jibril arranging the ranks of the angels?”
