«اِلْكِتَابِ انْكَتَبْ وِالْمَهْرْ عَلَى الله»

The written marriage contract has been concluded, but the mahr, the payment the groom owes the bride, is still unpaid. The speakers trust God to make it possible; they do not expect God literally to pay. The image is of a commitment made on paper while its heaviest burden is deferred and left to hope.

More broadly, it describes any undertaking where the easy, formal step is finished and the hardest portion remains. It can sound hopeful or gently ironic, pointing out that the real work or expense has only been postponed.

Use it wryly when a plan has been formally launched or agreed to, but its most demanding part, often the money, is still unresolved. The line pairs mild humor with hope and fits casual talk about weddings, projects, or deals left half-settled.
