Abu Dhabi has cancelled all permits for Ramadan tents in the emirate this year.
The move is in line with procedures issued by the National Emergency Crisis and Disasters Management Authority to prevent large gatherings.
It follows a federal rule announced in mid-March banning the use of communal tents, which are traditionally used to distribute free iftar meals.
Crisis authorities in Sharjah, Dubai and Ajman all previously prohibited the use of Ramadan tents.
Muslims will celebrate the second Ramadan of the coronavirus pandemic in little over a week’s time.
Mosques will remain open this year, but precautions remain.
Worshippers must also take their own prayer mats and copies of the Quran, and follow social-distancing protocols.
The holy month is expected to begin around April 12, but this will depend on the sighting of the new moon.
The start of the month is announced once a country’s Moon-sighting committee spots the new crescent.
Ramadan is the ninth month of the Islamic calendar and will last either 29 or 30 days, until the next new moon is seen.
On Thursday, the UAE Fatwa Council held an online meeting to discuss Covid-19 regulations during the holy month.
The council, chaired by Sheikh Abdallah bin Bayyah, said that taking the Covid-19 vaccine "does not invalidate fasting".
Further announcements regarding Ramadan are due to be made at the country's regular Covid-19 briefing on Tuesday.
