Is it true that speaking evil, such as a woman saying, "I will not marry off my daughters; rather, I will keep them with me," and then they do not get married, is considered a cause for evil to occur based on people's words?

A Muslim should accustom their tongue to goodness and not expect evil for themselves, but rather ask Allah for well-being. It has been reported in some narrations that affliction is entrusted to speech (al-balā’u muwakkalun bi al-mantiq). Although the muhaddithūn (hadith scholars) deemed its attribution to the Prophet weak, Ibn al-Jawzi included it in his collection of fabricated narrations (al-Mawḍūʿāt). However, its meaning is supported by the Prophet's (peace be upon him) statement to the Bedouin who wished for fever, and the Prophet agreed with him. This meaning has been mentioned by prominent scholars of the Ummah and has a basis in the apparent meanings of religious texts, experience, and observation. Ibn al-Qayyim explained this by stating that Allah has made these occurrences necessities for the effect of the affliction that happens upon uttering it, especially if the speaker is someone whose tongue is accustomed to speaking the truth. What further confirms this meaning is what people have witnessed regarding the realization of affliction after uttering it, as in the story of the old man whom the Prophet (peace be upon him) visited.
