Mukhtasar Bukhari (Abridged) 389 — Obligation of congregational prayer

Narrated Abu Huraira (may Allah be pleased with him): (On one occasion) the Messenger of Allah (peace and blessings of Allah be upon him) said: "By Him in Whose Hand is my soul, I have indeed intended to order that firewood be collected, then order for the call to prayer to be given for the prayer, then appoint a man to lead the people in prayer, and I would go to some people and burn their houses over them. By Him in Whose Hand is my soul, if any one of them knew that he would find a fat bone or two good pieces of meat, he would surely come to the 'Isha prayer."
