Rituals by themselves do not bring about the change in the human personality that Allah, through the Quran, expects of us. When the character building principles are reduced to rituals we are only “acting the part” without the benefits. When we study the true meaning of the Quran, the words should become “flesh and blood”, not in the Christian sense, but in the sense that we think, breathe, and act Quran. Quranic words have lost their pure Quranic meaning and are subjected to human interpretation, mostly Zoroastrian influences.
When characters are built through the corret principles then some may want to express this in rituals but this is the end result of the process, not the beginning. The Messenger showed us the way to implement the Quran, but mans nature is to see the world in a religious sense, where worshipping a God is required, so rituals were added to the Quranic processes. These then became more and more important; getting the right movement, placing the fingers here, having crisply ironed white clothes, and the principles were lost in history.
Rituals that bind communities together are only important if they have substance.
