16th Century – 1599 CE

On the road to the city of Dibba al Fujairah, 35 km to the north of the city of Fujairah and is also named in some cases, the Othmanian Mosque.
Al Bidya Mosque is characterized by architectural and structural component in roofing, where no timber was used to raise the roof, but depends on the column in the middle. This column holds the four domes of the Mosque in a wonderful architectural system where every dome is made up of three domes placed on top of each other. The large dome first, then the smaller dome, and a third with a tiny head. These domes are neighboring each other, located not far from each other. The Mosque features carvings that is architectural in nature and has a niche and a small platform and has internal openings for ventilvations and shelves. This Mosque is the oldest Mosque.
Pursuant to the most recent research initiative, conducted in partnership with the Petroleum Institute in Abu Dhabi in 2017, a study was undertaken to investigate the historical provenance of the mosque. Samples were extracted from the mosque's foundations and submitted to the (University of Minnesota) United States of America, for Uranium-Thorium radiometric dating analysis. The findings established that the construction of the mosque dates to the sixteenth century CE, specifically to approximately 1599 CE, with a margin of error of ±9 years.
The mosque underwent restoration and was officially reopened in March 2003
