Islamic Interpretation of Dreams (Ibn-i Sirin):

(Alimony; Maintenance) To provide support for one’s family and relatives in a dream mean prosperity, protection for one’s children and concern for one’s posterity. Whatever expenses one spends to support his family in a dream will be money he will receive in wakefulness.

If one finds himself unwillingly giving family support or alimony to his wife in a dream, it means hypocrisy, or that he is nearing his death.
