Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "By the One in whose hand is my soul! If I were invited to eat a trotter, I would accept, and if a foreleg or shoulder were given to me as a gift, I would accept." But Waki' did not mention the words "By the One in whose hand is my soul".
