Prayers are designed to raise God-consciousness five times a day, throughout one's life. Prayers also provide regular exercise - like yoga or Tai Chi or Qigong built into the day - and serve as a calming retreat from the daily demands of life. Muslims thus learn to balance deeni wa dunyavi (the spiritual and the worldly). They can't abandon one for the other; that's the essence of their faith.
Allah never changes a people's state unless they change what's in themselves
