Islamic Interpretation of Dreams (Ibn-i Sirin):
(Money) In a dream, a banana means money, savings, a fetus, a man in his grave, a prisoner in his jail, a closed book, news from the past, or it could mean inner knowledge.
In a dream, a banana also signifies clothing, love, tenderness, a generous man, a monotheist, or it could represent a person of good conduct.
If a banana tree grows inside one’s house in a dream, it means that he may beget a son. Eating a banana in a dream means profits from a business partnership.
For a business man, banana in a dream represents profits and for a renunciate it means devotion and ascetic detachment.
If a sick person eats a banana in a dream, it means aggravation of his illness or his death.
