Five times a day to good health

Muslims who pray five times a day stay healthy. This is beacuse their routine of praying innvolves several yogic and breathing exercises. So this is what keeps them fit.

In addition to this is "the aazaan" ... thats essentially a breathing excercies workshop. It can only enhance your health.

Vajrasana - Those who sit in this Asana have a quite steady and firm pose. They cannot be easily shaken. The knees are rendered very hard. This Asana resembles more or less the Namaz pose in which the Muslims sit for prayer.

One of the most obvious correspondences between Islam and yoga is the resemblance of salat to the physical exercises of yoga asanas.

The meaning of the word salat is 'to bend the lower back', as in yoga; the Persians translated this concept with the word namaz, from a verbal root meaning 'to bow'. The genius of Islamic salat is to incorporate all of these in rudimentary form into a compact, flowing sequence, ensuring a thorough, all-round course of exercises for good health that is easy for everyone to practice.

Namaz .. five times .. fifty times ?

The supreme wanted men to pray 50 times a day, but when appealed for a less difficult routine, it was resolved that there should be five prayers a day. This has remained the practice ever since.
