Musnad Ahmad 30:3087

Muhammad ibn Ja'far narrated to us, he said: Shu'bah narrated to us, from Sulayman, from Dhakwan, from Abu Hurayrah, from the Prophet, may Allah bless him and grant him peace, that he said: "If one of them—or one of you—were promised two good targets, or a bone with some meat from a fat sheep, they would all come for it. And if they knew what was in them—meaning the Isha and the Fajr prayers—they would come to them even if they had to crawl. I have indeed considered ordering a man to lead the people in prayer, then going to the people who stay behind from it—or from the prayer—and burning their houses down upon them."
