Sayyiduna Hulb al-Ta'i (may Allah be pleased with him) said: I was with the Prophet (peace and blessings be upon him) when a man came and said: There is a food that I feel uneasy about eating. He (peace and blessings be upon him) said: "Let nothing trouble your heart in which you would be resembling Christianity."
