Narrated: Abud Darda From Sunan Abu Dawood
I heard Rasulullah sallillahu alaihi wa sallam saying:
If there are three men in a village or in the desert among whom prayer is not offered (in a congregation), the devil has got the mastery over them.
So observe (prayer) in a congregation), for the wolf eats only the straggling animal.
Sa’ib said: By the word Jama’ah he meant saying a prayer in a company or in a congregation.
