‘Auf b. Malik told that the Prophet gave a decision between two men and that when the one against whom the decision had been given turned away he said, “My sufficiency is God, and good is the Guardian." Thereupon the Prophet said, “God most high blames for falling short, hut apply intelligence, and when a matter gets the better of you say, 'My sufficiency is God, and good is the Guardian’. (Al-Qur’an, 3:173) Abu Dawud transmitted it.
