If a poor person sees in a dream that he has entered into partnership with someone wealthier than himself, it is interpreted as wealth, and the poor person becomes rich.
Seeing a partnership in a dream signifies trade conducted in fear of Allah, or something whose worldly benefit will belong to the dreamer.
Seeing oneself enter into partnership with a known and familiar person signifies fairness and justice between the two. At times partnership also signifies love, sincerity, and keeping one's word.
