Defining Tatayyur (Taking Omens) and Pessimism, and Their Treatment

Question:
Many questions have reached us, and there is no harm in presenting those that relate to the topic from what remains with us. One of the brothers says: Honorable Shaykh, may Allah reward you with good, what is the definition of tatayyur (taking omens) and pessimism?

Answer:
I heard in lectures about taking omens, what is the best tongue or response? The Prophet (peace and blessings be upon him) said: , and he (peace and blessings be upon him) forbade it, and he said that it does not turn back a Muslim. If one of you sees something he dislikes, he should say: O Allah, none brings forth good deeds except You, and none averts evil deeds You. If something occurs in his heart, he says: This is , and do not let the evil deed , O Allah, there is no good except with You, and no omen except Your omen, and no god except You. This invalidates the pre-Islamic age of ignorance (jahiliyyah) concerns. For example, if he sees during his travel a camel that does not please him, or a donkey that does not please him, or a person that does not please him, he should not be concerned by it. Let him say: O Allah, none brings forth good deeds except You, and none averts evil deeds except You, and there is no power and no strength except with Allah. And he should not return from his need due to the pre-Islamic age of ignorance. If he goes out and believes it, it is a crow cawing, or he sees a donkey that does not please him, black or with a cut tail or such, and he becomes pessimistic, saying this journey will not succeed, or something similar. This is wrong. This is from the matters of the pre-Islamic age of ignorance. In the hadith: And Ibn Mas'ud said: "There is none of us but [who does it], but Allah makes it harmless through reliance (tawakkul). Taking omens is shirk (associating partners with Allah). Taking omens is shirk. There is none of us but [who does it], but Allah makes it harmless through reliance." This is what Ibn Mas'ud (may Allah be pleased with him) said.
The point is that taking omens is known in the pre-Islamic age of ignorance, and a person may be affected by it while being a Muslim, but it is treated. If something of this occurs in his heart, he should not mind it. He should strive against his self so that he does not perform the actions of the pre-Islamic age of ignorance, and he should say at that time: O Allah, none brings forth my good deeds except You, and none averts evil deeds except You, and there is no power and no strength except with [Allah], and he proceeds on his way.
And so with the pessimism in his heart from a bird or an animal, there is strength in him, the strength of faith and trust in Allah and reliance on Allah and worship of Allah, from Shaytan the accursed. And he says: O Allah, none brings forth my good deeds except You, and none averts evil deeds except You, and there is no power and no strength except with Allah. Yes.
