Mishkat al-Masabih #4079

'Abdallah b. Busr told that the Prophet had a dish called al-gharra' 1 which was carried by four men, and when they had offered the forenoon prayer that dish in which tharid had been prepared was brought and the people gathered round it. When they were numerous God's messenger knelt down, and when a nomadic Arab asked what kind of sitting that was, God’s messenger replied, "God has made me a kindly servant and not a refractory tyrant." He then said, "If you eat from its sides and leave the top a blessing will be conferred on it." 1. Meaning the white one. Abu Dawud transmitted it.
