«وكذلك لو بيَّنا نصيب رب المال وسكتا عن نصيب المضارب كان بيانًا»
“Likewise, specifying the capital provider's share while leaving the mudarib's share unstated supplies clarification.”
Reversing the named party does not change the principle. If the capital provider receives three-fifths of the profit, the working partner receives the remaining two-fifths. Both amounts belong to one total, so the first assignment determines the second mathematically.
Example: with a profit of 50,000, three-fifths yields 30,000 for the capital provider and 20,000 for the worker. This assumes the stated two-party division of the same profit.
The controlling question is whether the omitted share is actually determinate from the specified share. Multiple unidentified parties or additional conditions can defeat this simple inference.
