Salat is the name for the obligatory prayers which are performed five times a day, and are a direct link between the worshipper and God. There is no hierarchical authority in Islam, and no priests, so the prayers are led by a learned person who knows the Quran, chosen by the congregation. These five prayers contain verses from the Quran, and are said in Arabic, the language of the Revelation, but personal supplication can be offered in one’s own language. Because salat is transliterated from arabic word.

Prayers are said at dawn, noon, mid-afternoon, sunset and nightfall, and thus determine the rhythm of the entire day. Although it is preferable to worship together in a mosque, a Muslim may pray almost anywhere, such as in fields, offices, factories and universities. Visitors to the Muslim world are struck by the centrality of prayers in daily life.

When its time for Salat, They will call Adan( call for prayer), someone one will make Adan so everyone can hear, and everyone will start walking towards the mosque for Salat(prayer), the Muathan( the person who calls for prayer) will say:

God is Great.
