there are many events in "ramadan", islam's holiest month. during "ramadan", muslims must fast during the day. mosques organise "iftar" dinners after sunset. these are done after the fourth required prayer of the day. part of the food is given by members of the community, which creates nightly potluck dinners. the community contribution to these dinners is required. for this reason, mosques with smaller communities may not be able to hold the "iftar" dinners daily.
