What is the ruling on the money received by a graphic designer after the closure of the shop for which a work of art was commissioned, given that he completed most of the design and received two-thirds of the agreed-upon fee?

The aforementioned contract is closer to a 'contract of manufacturing' (istisna'a), which is permissible with its conditions. The shop owners are allowed to annul it due to harm caused by the shop's closure. They must pay you for the work you have completed, based on the Prophet's (peace be upon him) saying: "There should be no harm nor reciprocal harm." The agreed-upon price should be divided proportionally to what has been completed and what remains. The portion corresponding to what has been completed becomes due, and the portion corresponding to what remains is forfeited. Reconciliation between the two parties is recommended.
