The legislative provisions shall apply to all matters dealt with by those provisions in the letter and in the spirit . There shall be no scope for innovative reasoning in the case of provisions of definitive import . If the judge finds no provision in this Law, he must pass judgment according to the Islamic sharīʿa. Provided that he must have regard to the choice of the most appropriate solution from the schools of Imam Malik and Imam Ahmad bin Hanbal, and if none is found there, then from the schools of Imam al-Shafiʿi and Imam Abu Hanifa as dictated by expediency.

If the judge does not find the solution there, then he must render judgment in accordance with custom, but provided that the custom is not in conflict with public order or morals, and if a custom is particular to a given emirate, then the effect of it will apply to that emirate.
