Sahih Bukhari Volume 9, Book 92, Hadith Number 416.

Narrated By Jabir bin ‘Abdullah : When the (following) Verse was revealed to Allah’s Apostle: ‘Say: He has power to send torment on you from above,’…(6.65) he said, “O Allah! I seek refuge with Your Face (from that punishment).” And when this was revealed: ‘…or from beneath your feet.’ (6.65) he said, “O Allah! I seek refuge with Your Face (from that).” And when this Verse was revealed: ‘…or to cover you with confusion in party-strife, and make you to taste the violence of one another,’…(6.65) he said: “These two warnings are easier (than the previous ones).”
