Muslims marking today's Hari Raya Haji festival by praying yesterday evening at Singapore's newest mosque, Maarof Mosque, which opened last month in Jurong West. They also recited the takbir in celebration of the festival. The takbir proclaims the greatness of God and is recited after the five daily prayers for three days following Hari Raya Haji, as well as on the day itself. Many also broke their fast at the mosque yesterday. Muslims believe that fasting on the day before Hari Raya Haji is an act of devotion by which their sins can be forgiven by God.
