Sayyiduna Hulb al-Ta'i (may Allah be pleased with him) said: I heard the Prophet of Allah (peace and blessings be upon him) when a man asked him (peace and blessings be upon him), saying: There are some foods 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."
