Salah is the daily ritual prayer enjoined upon all Muslims as one of the five Pillars of Islam. It is to be performed five times a day. Salah is a precise worship, different from praying on the inspiration of the moment. Muslims pray or, perhaps more correctly, worship five times throughout the day: between first light and sunrise, after the sun has passed the middle of the sky, between mid-afternoon and sunset, between sunset and the last light of the day, between darkness and midnight. Each prayer may take at least 5 minutes, but it may be lengthened as a person wishes. Muslims can pray in any clean environment, alone or together, in a mosque or at home, at work or on the road, indoors or out. Under special circumstances, such as illness, or travel, certain allowances in the prayers are given to make their offering easy. Having specific times each day to be close to God helps Muslims remain aware of the importance of their faith, and the role it plays in every part of life. They serve as a constant reminder throughout the day to help keep believers mindful of God in the daily stress of work, family, and distractions of life, and are an oasis of solace. Prayer strengthens faith, dependence on God, and puts daily life within the perspective of life to come after death and the last judgment.
