Sahih Muslim
The Book Pertaining to the Turmoil and Portents of the Last Hour (Kitab Al-Fitan wa Ashrat As-Saah)
Book Number: 041 / Hadith Number: 7027
Abu Zur'a reported that there was a discussion in the presence of Marwan about the Last Hour, and Abdullah b. 'Amr said: I heard Allah's Messenger (may peace be upon him) as saying. The rest of the hadith is the same, but there is no mention of forenoon.
