No people sit in any gathering, mentioning Allah therein, except that the angels surround them, Mercy enshrouds them, and Allah mentions them to those near Him.

The final section of 130 Hadeeth on Manners, Section Six: Remembrance & Supplications, consists of only supplications to memorize.

It is authentically reported from the hadeeth of Anas that "Supplication is the core of worship."

The Prophet (may Allah raise his rank and grant him peace) explained the "baaqiyaat saalihaat" (never-ending righteous things) as: five phrases of Allah's remembrance in a hadeeth narration we studied.

Sitting in gatherings devoid of Allah's mention, where no salaat is sent upon the Prophet (may Allah raise his rank and grant him peace), will be a source of regret on the Day of Judgment.
