All Muslims are required to pray five times a day and mosques are set up around the town to call them to prayer during the course of the day. To make sure all can hear the call, mosques are built in every community, every section of town. This is the one closest to our home, a small one that probably would serve a small community of worshipers in the area (as I understand it, they must go to the mosque on Friday but other days they pray wherever they are). It is interesting to listen to muezzin, the man assigned to call all Muslims to prayer, as he sings the message to the community from the top of the minaret. While in the past, it was the force of his voice alone that was carried across the community, now the call is frequently assisted by PA systems.
It reminds you that you're in a completely different world, one with a culutre far older than anything we can imagine.
