“So wrongdoing must be understood by standing it against righteousness” explained Abdel Hamid, holding out his hands “like right against left”. He turned one hand over and then the other. He paused to take note of whether Rustam Bey was still with him. “Righteousness is good morality but it is also that about which the soul feels tranquil and the heart feels tranquil. This is what the Prophet said to Wabisah bin Ma’bad. As for wrongdoing Nawas bin Sam’an said he heard the Prophet saying that wrongdoing is that which wavers in the soul and which you dislike people finding out about, and Wabisah bin Ma’bad said that he heard the Prophet saying that wrongdoing is that which wavers in the soul and moves to and fro in the breast even though people again and again have given you their legal opinion in its favour. Both of these traditions came from imams with a good chain of authorities, one from Imam Ahmad Ibn Hanbal and the other from Imam Al-Darimi, may God be pleased with them both. So no doubt that these things were said by the Prophet, peace be upon him.” ― Louis de Bernières, Birds Without Wings
