Turag River

The Turag River is the upper tributary of the Buriganga, a major river in Bangladesh. The Turag originates from the Bangshi River, the latter an important tributary of the Dhaleshwari River, flows through Gazipur and joins the Buriganga at Mirpur in Dhaka District. It is navigable by boat all year round.
Tabligh Jam'at, a popular Islamic movement originating in South Asia, initially took hold in Dhaka in the 1950s as Maulana Abdul Aziz and other leaders set up the regional headquarters at the Kakrail Mosque near Ramna Park. An initiative of the movement is an emphasis on the six u??l or "basic principles," two of which include ilm, the pursuit of knowledge, and dhikr or zikr, a method of prayer involving repetitive invocation of hadith and Qur'an passages. To this end, the movement places importance on ijtema or assembly, where members gather to practice and participate in dhikr, hear religious sermons and discuss their activities.
The largest of these, the Bishwa Ijtema, is situated by the Turag River in Tongi and attracts estimates of between two to four million Muslims annually as well as representatives from over sixty countries, making it the second biggest Islamic congregation after the Hajj.
