Dear Br. Jawaid
Is the below ayet is just useless. Allah gave such detailed instruction on preparation as never before in any other book. Why?
All this preparation and do nothing?
5:6 O You who have chosen to be graced with belief! When you congregate for Salat, wash your faces and your forearms, hands to the elbows. Lightly rub you heads and your feet to the ankles. If you are in a state of ceremonial impurity, bathe your whole body. But, if you are ill or traveling, or coming from the privy, or are in a state of ceremonial impurity and find no water, then take clean sand or earth and lightly rub your faces and hands. (This will help you prepare mentally for congregational prayer 4:43). Allah does not wish to place upon you any difficulty, but to make you clean and to perfect His blessings upon you, that you be grateful.
Now about the salat procedure, since it has not been given, which is always quoted by followers and non-followers both to support their point of view.
Answer. Salat was not Mohammedan, it was a continuation form Prophet Abraham time in some form in those tribes. For some unknown reason so far, Allah Pak never gave any new procedure to prophet Mohamad(s). In his infinite wisdom, HE never wanted Mohammad(s) to change the continuation.
My guess is that in far future, human beings will not be able to perform it in present way, due to changes in life style, space, control of anti-religion forces on earth, bondages or any other reason, not known today. Or may be human will be on other planets as well, where physical performance is not possible.
Allah's infinite wisdom knows best. We can not see in future beyond our noses. Our usual thinkings are around our time and not much beyond.
Even today, physical salat is performed in hundred different ways and no one is wrong. The objective is intention and action.
