What is the ruling on organizing promotional marketing exhibitions such as Gitex Dubai and the Dubai International Motor Show, given the occasional presence of music and immodestly dressed women, for an organizer who adheres to Islamic guidelines and cannot enforce them on all participants, but encourages them to do so and exerts his utmost effort to prevent violations? Is it better to abandon this work to other companies that do not follow Islamic law, or to remain and attempt reform?

The work of organizing marketing exhibitions for cars falls under the category of Ijarah (definition) (leasing/hiring), which is permissible in principle, unless the contract includes the use of forbidden promotional means, such as the use of unveiled women and music. If any of that occurs on the part of the participating companies, the organizing company is not held accountable if it is unable to prevent it. However, if it is able to prevent it, then it is obligated to do so. The Ijarah contract remains valid and the rent is permissible because the primary benefit is permissible.
