The Best Worship

The best worship occurs with the combination of speech and reflection. When practiced for a long time regularly, one achieves supreme realizations about God the Exalted and His acts. When one reflects deeply, he separates himself from others and even from his own limitations.

The believer sees good in all things, even in affliction and trial, in which there is wisdom: an opportunity to grow, purify oneself, learn patience, and draw near to God.

It may be that you dislike something though it is good for you, and it may be that you love something though it is bad for you. (Quran,2:216)

Understanding this is the idea in witnessing God's wisdom in events of the world.
