Salah or Prayer
Salah is the name for the obligatory prayers that are performed five times a day, and are a direct link between the worshipper and God. There is no hierarchical authority in Islam and there are no priests. Prayers are led by a learned person who knows the Qur'an and is generally chosen by the congregation.
Prayers are said at dawn, mid-day, late-afternoon, sunset and nightfall, and thus determine the rhythm of the entire day. These five prescribed prayers contain verses from the Qur'an, and are said in Arabic, the language of the Revelation. Personal supplications, however, can be offered in one's own language and at any time.
Although it is preferable to worship together in a mosque, a Muslim may pray almost anywhere, such as in fields, offices, factories and universities. Oftentimes visitors to the Muslim world are struck by the centrality of prayers in daily life.
