The Book of Prayers (Kitab Al-Salat)
Muslim :: Book 4 : Hadith 1370
Abu Huraira reported Allah's Messenger (may peace be upon him) 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.
