Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) once mentioned the following:

All musjids in the world are branches of Musjid-e-Nabawi, the musjid of Rasulullah (sallallahu ‘alaihi wasallam). Hence, the Deeni efforts that used to take place in the Musjid of Rasulullah (sallallahu ‘alaihi wasallam) should be carried out in all musjids.

During the era of Rasulullah (sallallahu ‘alaihi wasallam), apart from the five daily salaah being performed in Musjid-e-Nabawi, Rasulullah (sallallahu ‘alaihi wasallam) would impart the knowledge of Deen to the Sahaabah (radhiyallahu ‘anhum) and make an effort upon their Deeni reformation. Together with this, Rasulullah (sallallahu ‘alaihi wasallam) would send jamaats to the various areas to propagate Deen to the people or to educate them regarding Deeni matters.
