Respectfully, Dr Saab, individuals have already made changes to the Quranic way of life and we have ended up with the ritualised, physical prostrations of the namaaz instead of the life enhancing, practical and mind-willing acceptance of the values and principles of the Quran. Allama Parwez knew very well what Salat was but could not openly say that the namaaz should be rejected because of the society he lived in [Ghamdi has left Pakistan after death threats and what controversy has he said? very little compared to the hell that the Mullahs would unleash upon any man who denies namaaz!]. That was why Parwez gave a whole list of what Salat is all about and only at the end put his “get out of stoning to death” sentence about a ritual aspect to it. He expected us to understand the truth and do the 99% of what Salat is and then think about the ritual, whereas today it is 100% ritual.
Sujood is about mental submission/acceptance but where this is mentioned in the Quran it is understood by some to be physical prostration, just like Adam is seen to be an individual man, and not mankind.
The clincher for any thinker should be “birds know their salat”, I have seen parrots talk but none have congregated for namaz!
4:41 Do you not realize that Allah, He it is Whom all beings in the heavens and the earth glorify, and the birds, with their wings outspread, as they fly in columns. All of them know their SALAT and TASBEEH (mission and strife). Allah is Aware of what they do to fulfill His Plan.
