Later, officials announced that the moon had been sighted and Taraweeh would begin from Sunday night.
Arab News reports that the moon was also seen in the United Arab Emirates and Qatar.
Ramadan is the ninth month of the Islamic calendar, during which Muslims fast from dawn to sunset, abstaining from food and drink.
The holy month is a time of introspection and community, when Muslims read the Quran more than usual, perform taraweeh prayers and increase their good deeds, including charity.
