The 53rd Biswa Ijtema, the second largest congregation of the Muslims, will begin on Friday on the bank of the Turag River at Tongi on the outskirts of Dhaka.
The first phase of the three-day Ijtema will begin with 'Aam Bayan' (general sermons) by noted scholars after Fazr prayers that will end with Akheri Munajat (final prayers) on January 14.
Thousands of devotees from home and abroad started to throng the Ijtema ground on the bank of the Turag since Wednesday night to take part in the religious event seeking divine blessings of the Almighty Allah.
The second phase of the Tongi Ijtema will begin on January 19 at the same venue and it is scheduled to end with Akheri Munajat (final prayers) on January 21.
Tablig Jamaat has been organizing the Ijtema at this venue since 1967, says BSS.
However, the Ijtema is held in two phases since 2011 to ease the accommodation problem.
President Abdul Hamid and Prime Minister Sheikh Hasina Thursday issued separate messages greeting the Muslim devotees all over the world on the occasion of the Bishwa Ijtema.
In the messages, the President and the Prime Minister wished all success of the three-day congregation.
An eight-tier security measure will be taken with deployment of 7,000 policemen and about 250 RAB members to avert any untoward incident during the Ijtema, law enforcement agency sources said.
According to the sources, 15 watch towers and 41 close circuit camera televisions have been set up in and around the Ijtema ground alongside deployment of bomb disposal units and dog squads to ensure foolproof security of the Biswa Ijtema.
Fifty medical teams and 14 ambulances will provide health care services to the devotees during the three-day congregation.
