Salah (prayer) is one of the most important pillars of Islam. The payer is the communication between the Creator and His most wise creator the human being. It is the obligation upon all mature, sensible Muslim men and women. Muslims are commanded to teach the five prayers to their kids at the age of seven to 10, so that may develop a habit to do it once it becomes an obligation upon them once they will become mature at the age of 15.
