What did the Prophet Muhammad (peace be upon him) say about Friday and the time when it is possible to make a request to Allah (swt)?
 Narrated Abu Huraira:                     Allah's Apostle (p.b.u.h) talked about Friday and said, "There is an hour (opportune time) on Friday and if a Muslim gets it while praying and asks something from Allah, then Allah will definitely meet his demand." And he (the Prophet) pointed out the shortness of that time with his hands.
