Musnad Ahmad 30:210

Sufyan narrated to us, from Abu al-Zinad, from al-A’raj, from Abu Hurairah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "I have indeed considered ordering a man to establish the prayer, then I would order my young men—and Sufyan said once: young men—to go to a people who do not attend it, and they would burn their houses down upon them with bundles of firewood. And if one of you knew that he would find a meaty bone or two good trotters, he would certainly attend the prayer." And Sufyan said once: "The Isha prayer."
