‘Urwa b. ‘Amir told that when taking omens was mentioned in the presence of God’s messenger he replied that the best type was the good omen, adding that a Muslim is not turned back from anything because of an omen. He told them that when any of them saw anything he disliked he should say, “O God, Thou alone bringest good things, Thou alone avertest evil things, and there is no might or power but in God.” Abu Dawud transmitted it in mursal form.
