What did Prophet Muhammad (saw) say about the Hour being established?
 Narrated Abu Huraira:                     Allah's Apostle said, "The Hour will not be established till the buttocks of the women of the tribe of Daus move while going round Dhi-al-Khalasa." Dhi-al-Khalasa was the idol of the Daus tribe which they used to worship in the Pre Islamic Period of ignorance.
