Salah is an Arabic word to mean a spiritual relationship and communication between the creature and his Creator. Salah is one of the five pillars of Islam. A special communication (Salah) is to take place five times a day for a Muslim: Fajr (Dawn), Zuhr (Noon), 'Asr (Afternoon), Magrib (Sunset), and 'Ishha' (Late Night).
Salah is to be performed with mental concentration, verbal communication, vocal recitation, and physical movement to attain the spiritual uplift, peace, harmony, and concord. There is a congregational prayer on Friday noon (Salatul Jumu'ah) with a sermon (Khutbah) to be delivered by a religious leader (Imam) called Khatib.
To perform Salah, a Muslim has to have ablution (Wudhu'). He/she should make sure that cleanliness of body, clothing, and place are attained before performing Salah.
Salah is not to be confused with prayer; the latter could be interpreted as supplication (Du'a).
