Sahih Bukhari | Volume 6 | Hadith Number 152

Narrated by Jabir
When this Verse was revealed: "Say: He has power to send torment on you from above." (6:65) Allah's Apostle said, "O Allah! I seek refuge with Your Face (from this punishment)." And when the verse: "or send torment from below your feet," (was revealed), Allah's Apostle said, "(O Allah!) I seek refuge with Your Face (from this punishment)." (But when there was revealed): "Or confuse you in party strife and make you to taste the violence of one another." (6:65) Allah's Apostle said, "This is lighter (or, this is easier)."
