It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that a man came to the presence of the Prophet and said, "O Messenger of Allah (peace and blessings be upon him), such thoughts and whispers come to my heart that I would prefer to fall from the sky rather than utter them with my tongue (what should I do?)" The Noble Prophet (peace and blessings be upon him) said, "This is clear faith."
