This is how Rasulullah (s.a.w) praised the congregations of people who come together and form a circle for the purpose of dhikr:
One day, Rasulullah (s.a.w) came across a circle formed for the purpose of performing dhikr and said:
Then he honored them by sitting among them.
Rasulullah (s.a.w), who honored this gathering of ‘ilm (divine knowledge) and dhikr with his presence and his heart (which adorns heaven), does not abandon those who safeguard this amanah, who form a circle for Allah, who sit and make dhikr of almighty Allah, who learn the ilm which is his sole legacy. With Allah’s permission, he honours this poor Ummah (Islamic society) with his spiritual presence and supports them with his love and prayers.
“If the people knew the virtue of gathering for Khatme/dhikr, they would come to Khatme even if ill or disabled, crawling on their hands and knees [if necessary]. Because the spiritual leader of Khatme is Rasulullah (s.a.w). He honours these gatherings with his spiritual presence and he carries the wishes of the congregation to Allah Ta’ala. Could anything carried by Rasulullah (s.a.w) to the Divine Presence ever be rejected?”
