Musannaf Ibn Abi Shaybah

Hazrat Nafi’ bin Jubair narrates that Hazrat Ka’b asked Hazrat Abdullah bin Amr (may Allah be pleased with him): “Is there such a thing as bad omen?” He replied: “Yes!” He asked: “Then what supplication do you recite?” He replied: “I recite this supplication: Translation: O Allah! There is no bad omen except Your bad omen. And there is no good except Your good. And we have no Lord besides You.” Hazrat Ka’b said: “You are the greatest jurist among the Arabs.”
