Granting the possibility that Islam is a divinely inspired religion, then I would like to know what benefits one gets from praying 5 times a day? What exactly, specifically, is happening to one's physical/spiritual/psychological constitution as they pray Fajr, Zuhur, Asr, Maghrib and Isha?

Is praying in a dynamic way like the Muslims, in those highly specific postures giving any different benefits than say when Catholics are at Mass, just standing sitting and kneeling?

What is the significance of praying 5 times a day at particular times of the day? Thank you in advance.

Also, a little side question, what are the benefits of doing Wudhu/ablution?
