If you are interested in how a mosque functions, visit here during a Friday. A large number of Muslims gather at the Grand Mosque. If it is during Eid, the number could even rise up to 40,000. It is better to approach Sheikh Zayed Grand Mosque Center first to get an idea about the mosque's customs and rituals. The office also manages the mosque's daily operations. The mosque is usually crowded as a place of worship, Friday gathering and also as a centre for learning. The mosque has several programmes meant for visitors keen on learning Islam.
