«اِلْمَشْرُوطَهْ مَحْطُوطَهْ»

The saying holds that whatever has been made a condition of an arrangement is already fixed and owed. Once terms are settled, the obligation stands, and no amount of pleading or maneuvering will make it disappear.

In practice it shuts down attempts to renegotiate or wriggle out of a commitment. The speaker reminds the other party that resisting is useless and that the sensible course is simply to deliver what was promised.

Use it when someone tries to bargain down, delay, or dodge something already agreed, such as a fee, a share, or a promised obligation. It tells them firmly that the matter is closed and must be honored.
