It is narrated from Saeed bin Musayyib, may Allah have mercy on him, he says: I asked Sayyiduna Sa’d bin Abi Waqqas, may Allah be pleased with him, about bad omens, but he scolded me and said: Who told you this? I did not like to tell him who had told me, then Sayyiduna Sa’d, may Allah be pleased with him, stated that the Noble Prophet, peace and blessings be upon him, said: There is no contagious disease, no bad omen, and no evil in the owl. If there were to be any bad omen in anything, it would be in the horse, the woman, and the house. When you hear that there is plague in a land, then do not go there, and when you are in a land where plague has broken out, then do not leave from there.

Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) said: Whoever is deterred from doing something by bad omen has committed shirk. The people asked: O Messenger of Allah! What is its expiation? He (peace and blessings be upon him) said: Its expiation is to say: O Allah! There is no good except Your good, and there is no omen except Your omen.

Abu Zubair says: I asked Sayyiduna Jabir (may Allah be pleased with him) whether the Messenger of Allah (peace and blessings be upon him) said anything about bad omens and the contagiousness of disease. He said: I heard the Noble Prophet (peace and blessings be upon him) say: Every man's omen is in his own neck.

It is narrated from Sayyiduna Muawiyah bin Hakam Sulami (may Allah be pleased with him), he says: I said, "O Messenger of Allah! Tell us about those things which we used to do in the days of ignorance, for example, we used to take bad omens." The Messenger of Allah (peace and blessings be upon him) said: "This is a thing which you may feel in your heart, but it should not become an obstacle for you." I said: "One thing was also that we used to go to soothsayers and astrologers." He (peace and blessings be upon him) said: "Do not go to soothsayers."

Sayyida Umm Karz Ka'biyyah (may Allah be pleased with her) narrates that I heard the Noble Prophet (peace and blessings be upon him) say: Let the birds remain in their nests.

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Taking bad omens is shirk, and each one of us may be afflicted by this suspicion, but Allah Almighty removes it through reliance (tawakkul) upon Him.

It is narrated from Sayyiduna Fadl bin Abbas (may Allah be pleased with them both), he says: One day I went out with the Noble Prophet (peace and blessings be upon him), when suddenly a deer appeared and it turned to the left side. I clung to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! Have you taken it as a bad omen? The Prophet (peace and blessings be upon him) said: A bad omen is that which prompts one to act or turns one back from doing something.
