Islam is devoutly followed by most Zamindars and it seems to be the uniting factor among them. They do not evaluate each other on the basis of caste. They believe that all belong to one caste and that it is Islam. To the Zamindars, the caste system borrowed from the Hindus is the equivalent of an occupational class structure. People celebrate every religious holiday and occasion. The wealthy Zamindars send food, sweets, and drinks to the mosque during the month of Ramadan (the fasting month). Prayers are said five times a day in the mosque over the loudspeakers. The people have put their faith in the hands of God, because they believe that God does not punish but helps. Zamindars also believe that while People must strive for a prosperous life, they must not let the material attachments of life hold them down. It is through prayers that they reach toward God and depend on his help. Zamindars in more easterly parts of the Indo-Gangetic plain tend to be Hindus, except for those in Bangladesh who again are Muslim.
