Masjid Zarooni, also known as the Small Kottai Masjid, is a modest mosque located in the Ayal Nasir area of Deira, Dubai. Situated at 78F3+QC5 on 17B Street, it is in proximity to landmarks such as the Naif Police Station and the Mobile Plaza Building.

The mosque is known for its cultural diversity, often referred to by the local community as the “Bangali Masjid” or “Tamil Masjid,” reflecting the multicultural congregation it serves. Despite its smaller size, it can accommodate up to 2,500 worshippers during peak times. However, due to its popularity, it tends to be crowded, especially during Friday prayers and religious events.
