Narrated [Abu Hurairah (RA)]:
Allah's Messenger (ﷺ) mentioned the day of al-Jumu'ah and then said, "There is a time in it (Friday) at which no Muslim would stand up while praying and beg Allah, Who is Great and Glorious, for something except that He would give it to him. He (ﷺ) indicated with his hand that it (this time) is short."

[Agreed upon].
