Millions of people whose relatives have been murdered, most of them have been mutilated, tortured, exiled from their countries, burning with homesickness, call a common prayer in the countries where they take refuge. They all have one desire - to return to their hometown before they die. Every year, five million Muslims from 150 different countries get together in Bangladesh for three days to pray for persecuted Muslims and world peace. It is the second largest religious gathering after the Hajj.
