Can a man be a bad omen, causing diseases, misfortunes, and obstacles for his fiancée?

The Islamic law forbids pessimism (tashā'um) and omens (taṭayyur), establishing that everything that occurs in the universe is by the divine decree (qaḍāʾ) and predestination (qadar), written fifty thousand years before the creation of the heavens and the earth. The people of the town said to the messengers, "Indeed, we augur evil from you" (Innā taṭayyarnā bikum), and the messengers replied that their evil omen was with them (i.e., their deeds and their provisions). It is not permissible to attribute evil to someone who has no involvement in it; rather, it is in accordance with divine decree and predestination. A Muslim must be content and submit, and stay away from omens, which are forbidden. The Prophet, peace and blessings be upon him, said: "There is no adwa (transference of disease without the will of Allah), no ṭiyara (bad omens), no hama (belief in omens from owls), and no Safar (belief in omens from the month of Safar)." And whoever is turned back from a need by an omen has committed shirk (polytheism). The expiation for that is to say: "O Allah, there is no good except Your good, and no omen except Your omen, and there is no god besides You." Omens are shirk, and Allah removes them through reliance upon Him.
