It is narrated from Sayyiduna Wabisah bin Ma’bad Asadi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to Wabisah:“Have you come to ask about virtue and sin?”I said: Yes. The Prophet (peace and blessings be upon him) joined his fingers together (made a fist) and struck it upon his chest and said:“Ask your soul and your heart. Virtue is that which the soul is at ease with and the heart feels tranquil about, and sin is that which causes uneasiness in the soul and hesitation in the heart, even if people give you a fatwa (legal verdict) permitting it.”
