Sahih Muslim Book 4, Hadith Number 1849.

Chapter : Observing of silence in sermon on Friday.

Abu Huraira reported Allah’s Messenger (may peace be upon him) as saying: There is a time on Friday at which no Muslim servant would pray and would ask Allah for a thing (that is good) but He would give it to him. Qutaiba pointed with the help of his hand that it (the time) is short.
