Can a wife be a source of good or bad luck for her husband, and what should she do to bring him good luck according to the Book and the Sunnah?

Pessimism and omens are reprehensible and indicate a weakness in one's trust in Allah. The Prophetic hadith that mentioned ill omens in a house, a woman, and a horse does not mean that these things inherently have an effect, but rather that it is by the permission of Allah Almighty. A righteous wife who is obedient to her Lord and her husband is a good omen and a blessing, while one who disobeys her Lord and rebels against her husband is an ill omen. Thus, ill omens and good fortune are related to the deeds and manners of people, not to their intrinsic natures. To achieve a good life, a woman must fear Allah, obey her husband, and raise her children according to the teachings of Islam.
