It is narrated from Hazrat Hilb (may Allah be pleased with him) that a man asked the Holy Prophet (peace and blessings be upon him) that there are some foods from which I feel disgust and I feel uneasy about them. So I heard the Holy Prophet (peace and blessings be upon him) saying that such doubts should not arise in your hearts as the Christians were afflicted with, and you too start doubting like them.
