Sahih Muslim | Book 40 | Hadith Number 6841

Narrated by Abu Huraira
Abu Huraira reported Allah's Messenger (may peace be upon him) as saying: If you survive for a time you would certainly see people who would have whips in their hands like the tail of an ox. They would get up in the morning under the wrath of Allah and they would get into the evening with the anger of Allah.
