One of the pillars of Islam is that Muslims pray five times a day. Before those prayers, they are expected to perform a purification ritual called Wudu, during which they wash their face, hands, arms and feet. We visited Masjid Muhammad Mosque in Washington, D.C. where Imam Talib Shareef described the ablution practice as preparing for an “appointment before God.” --- Religion& Ethics NewsWeekly http://www.pbs.org/religionethics
