The Sheikh Zayed Grand Mosque in Abu Dhabi was the vision of the UAE's founding president, Sheikh Zayed bin Sultan Al Nahyan, who is buried in the courtyard beside it. Completed in 2007, it holds more than 40,000 worshippers and is built of white Macedonian marble with 82 domes, over a thousand columns and reflective pools that double the building at night. Inside are the largest hand-knotted carpet in the world, made by Iranian weavers, and chandeliers of Swarovski crystal. Craftsmen from many countries worked on it, and floral marble inlay covers the courtyard. Non-Muslim visitors are welcome outside prayer times, with free guided tours and a dress code of loose clothing and headscarves for women.

Jumeirah Mosque, built in 1979 from pale stone in the medieval Fatimid style, has two minarets and a large central dome. It is one of the few mosques in Dubai that welcome non-Muslim visitors, on guided visits run under the Open Doors, Open Minds programme. The building is especially attractive when lit at dusk.

King Faisal Mosque in central Sharjah was opened in 1987 and named after King Faisal of Saudi Arabia, who gave it to the emirate. For many years it was the largest mosque in the UAE, with room for well over ten thousand worshippers. Its modern concrete design has two tall minarets, and it stands beside the Central Souq.

Sharjah Mosque, opened in 2019 at Tay on the Emirates Road, is the largest mosque in the emirate, with space for some 25,000 worshippers inside and in its courtyards. It is built in Ottoman style with a great central dome, smaller domes and two minarets. Non-Muslim visitors have their own viewing areas, and the grounds include gardens and fountains.

Sheikh Zayed Mosque in Fujairah is the second largest mosque in the UAE. Opened in 2015, it has six minarets about 100 metres high and a cluster of white domes, in a style inspired by Ottoman mosques. The prayer hall and courtyard together hold around 28,000 worshippers. It is striking when lit at night against the Hajar Mountains.

Al Badiyah, on the coast road north of Fujairah, is the oldest known mosque in the UAE, usually dated to around 1446. It is small and simple: four domes of different sizes resting on a single central pillar, walls of stone and mud plastered white, and a prayer hall that holds only a few dozen people. There is no minaret, which is unusual and points to its age. Watchtowers on the hill behind were built to guard the village and give a view over the mosque and the sea. It is still in use for prayer, and visitors are welcome outside prayer times if dressed modestly.
