Musannaf Ibn Abi Shayba 3:974

Abu Bakr narrated to us, he said: Abu Mu'awiyah narrated to us, from al-A'mash, from Abu Salih, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, the heaviest of prayers upon the hypocrites are the Isha prayer and the Fajr prayer. And if they knew what was in them, they would have come to them even if crawling. And I have indeed intended to order the prayer to be established, then order a man to lead the people in prayer, then I would go with men carrying bundles of firewood to a people who do not attend the prayer, and I would burn their houses down upon them with fire."
