Islamic Interpretation
In a dream, anointing oneself with oil signifies obtaining blessed and lawful income or recovering from an ailment, while drinking oil generally portends misfortune, an evil spell, or sickness. However, olive oil specifically symbolizes divine knowledge, profound wisdom, spiritual enlightenment, inner illumination, blessings, and righteous earnings. Consuming any other oil, such as from rapeseed or the terebinth tree, indicates acquiring wealth from dubious or illicit origins. Dreaming of oil can further represent the heart's radiance, spiritual advancement, deepening insight, or conversely, contraception, homicide, or the fracturing of bones. Oil may also denote a broker or intermediary. If wholesome oil becomes rancid in the dream, it signifies the breaking of a covenant, whereas if spoiled oil is restored to purity, it denotes increasing awareness, firm conviction, and the adoption of virtuous conduct in one's dealings.
