«مَا سِيلِ الَّا مِنْ كِيلْ»

The saying draws on a mill: the flowing here is flour streaming from the mill's outlet, not a flood, and it can never exceed the grain measured into the mill. Output is bound to input, so whatever a person receives mirrors what they have supplied.

As a general lesson, it reminds listeners that benefit follows contribution. Someone who gives little should not expect much in return, while generous investment of goods, effort, or care brings a correspondingly fuller yield.

Use it when someone expects generous returns without contributing, or to explain why a modest effort yields a modest result. It fits exchanges, work, hospitality, and relationships where what comes back depends directly on what one puts in.
