Abu Dawud Book 2, Hadith Number 547.

Chapter : Not known.

Narated By AbudDarda’ : I heard the Apostle of Allah (PBUH) say: If there are three men in a village or in the desert among whom prayer is not offered (in congregation), the devil has got the mastery over them. So observe (prayer) in congregation), for the wolf eats only the straggling animal. Sa’ib said: By the word Jama’ah he meant saying prayer in company or in congregation.
