The first phase of 53rd Biswa Ijtema, one of the largest religious congregations of the Muslim world, will conclude on Sunday with the offering of Akheri Munajat.
Sources said the Munajat will begin at around 11.00 am. Bangladesh's Maulana Jobair will conduct the Akheri Munajat at the first phase of Biswa Ijtema.
The first phase of Bishwa Ijtema began after Fazr prayers on Friday morning with religious sermon (Aam Boyan) by renowned Islamic scholars and prayers.
Lakhs of Muslim devotees across the world have joined the Bishwa Ijtema.
The Juma prayer of the Ijtema was also attended by thousands of Muslims.
An eight-tier security measure has been taken with deployment of 7,000 policemen and about 250 RAB members to avert any untoward incident during the Ijtema.
Some 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 are providing health care services to the devotees during the three-day congregation.
The second phase of Biswa Ijtema will begin on January 19 at the same venue and will end with Akheri Munajat on January 21.
Tablig Jamaat has been organising the Ijtema at this venue since 1967. However, the Ijtema is held in two phases since 2011 to ease the accommodation crisis..
