Sahih Muslim 651 b
Kitabu cha Misikiti na Mahali pa Kuswali
The virtue of prayer in congregation, and clarifying the stern warning against staying away from it, and that it is fard kifayah
Abu Huraira reported Allah's Messenger (ﷺ) as saying: The most burdensome prayers for the hypocrites are the night prayer and the morning prayer. If they were to know the blessings they have in store, they would have come to them, even though crawling, and I thought that I should order the prayer to be commenced and command a person to lead people in prayer, and I should then go along with some persons having a fagot of fuel with them to the people who have not attended the prayer (in congregation) and would burn their houses with fire.
