Namaz is not part of Salat, 100% agree but neither it is a part of establishing Just and fair society in the "corrupted countries" in the name of religion Islam.
This concept of establishing so called Islamic Socialism is an Utopian concept and root cause of dispute, conflict and disagreement between people of different beliefs.
We are still fighting among ourselves over which is the best translation of the book Quran and wish to establish our own version of Quranic society in the world. Isn't it strange?
This is not the intended message of the book Quran but the understanding of some respected souls who were concerned about the dilapidated condition of their country's governance.
There are so many countries who are not aware about the message of the book Quran but still are top in peace and happiness index. It is because they follow their common sense and did not rely on holy books for guidance.
Please don't misinterpret or convert the message of Love, Peace, Acceptance into the message of war, overpowering, conquering, capturing, spilling blood of others and establishing the rule of the book Quran which we ourselves are not clear and don't understand.
The book Quran is not a civics book nor it is a book of criminal, society or civil laws. It is a catalogue of how to develop, operate and handle our own nafs, soul, self.
