Biswa Ijtema, the second largest Muslim congregation after the Hajj has been taking place on yearly basis since the 1960s, first organized by the Tabliq-e-Jamaat. In 2010, it was held between January 22 and 24, on the bank of River Turag at Tongi, on the outskirts of Dhaka.

Islamic scholars from different countries delivered sermons on aspects of Islam. More than two million people, including a hundred thousand women and nine thousand devotees from abroad took part in the congregation.

A day or two before the event started, thousands of devotees with winter clothes, blankets and cooking apparatus across the country began gathering at the Ijtema venue where they began setting up makeshift tents to reside as the event went on. Transportation around Dhaka city became congested due to such amount of incoming people.

About eighteen thousand security personnel from different agencies kept an eye to strengthen surveillance with helicopters, speedboats and patrolling pickup vans. Finally on Sunday, the congregation was wrapped up with an ocean of four million people around the riverbank partaking in the concluding prayers (Akheri Monajat).
