Do you honestly believe GOD is that petty? So if I do not follow the cookie cutter prayer, then GOD is not pleased with that prayer? That is not an all-merciful act, nor a Just one. It is nonsensical from the perspective that if the details were of such importance that a prayer will not be accepted by GOD, why not include them, without question, in the Qur'an?
Bro humbleMuslim, your not arrogant person, so please try to understand.
Salah is not defined by a ritual form. That's just an outward form, it's not Salah. God says in Quran "woe to those whom do Salah, those whom are heedless in their Salah".
Just as Salah has an outward, it has inward. The Inward of the Outward is explained in Quran.
For example, why are we forced to do Salawat. We might not understand it, but see for example, the response of God for "why not a treasure..." and how God negated the love of Dunya through out.
The connection to God, how does it take place? Is it without a means? Or is through a means? You will see God says through a means "we made them Leaders whom guide by our command and revealed them the doing of good, and the establishment of Salah"
Salah was not simply outward. It has various ranks and stages. The outward form we have, it sort of body that is for all stages and suited for many states and remembrance.
Quran talks about bowing, prostration, glorifying God's Name, etc, reciting Quran, all this is talked about, but it didn't give us the exact form.
It doesn't even say we have to read Suratal Fatiha but Suratal Fatiha is the heart of Salah. You take it out, and it's spirit is gone.
We have to understand we don't understand all things right away. The outward is suppose to be a guide to look for explanation in Quran. We have that background and then we see with Quran, what are we remembering in Salah and what it has to do with connecting to God, his blessed Name and purpose of Salah.
If God put it all plain words the whole Shariah, people would not search the inward.
You would think for example, Salah is that outward command, and that's it. It's not explained that way. It has discipline.
See for example Wicked Willow. She sees these things as rituals with no deep purpose. Quran has explained the Inward wisdom, but to whom, to whom it was revealed. That Messenger (pbuh) is the whom clarified and taught it to the companions. The early believers understood the religion in deep manner. The later people whom converted due to the sword (as you know they would not accept peace so this was last alternative), they had no in depth understanding but at least they had the outward form.
Try to understand bro that Prophethood is not simply about giving us simply instructions. It's about revealing to us and guiding us to truths. It's about teaching the soul...
Some people do Salah but go blow themselves up in the masses. If they ever connected to God, they would not have done so. This is because they never searched out for the inward salah.
People sastified of the outward forms and don't want the treasured mercy of God, they are tricking themselves by the outward forms.
If you thought about why God wants you to testify to Mohammad (pbuh) Servanthood and Messengerhood, as well to bless him and his family, and read to find out why in God's book, the Sunnah and it's wisdom would become manifest and clear.
Instead for whatever reason you follow either your own or ignorant people opinion that Salah should not included Mohammad (pbuh) which is baseless because he is included no matter what in Suratal Fatiha and you can't deny him being Favored Servant as well if you recite some of the small Surahs', they are about him.
I warn you with love as a brother, to submit to the Sunnah bro for it's all contained in the Quran even if you don't preceive it. Iblees wants to Worship God directly, he did, got rewarded, but when he suppose to go to God through Adam (as), his Ego got in the way.
You want no one inbetween you and God's word, and rely on yourself, what if the a whole a lot is about trying us by this.. what if part of the Quran is about the door to enter to understand the Quran. See my name bro, the family I refer to is the elect family.
God wants us to approach him not arrogantly. Disbeleivers would say why doesn't God talk to them or bring down a sign to them, etc.. Your now asking why isn't this and this clear in Quran... We don't make demands on God and we don't say he would have to make it clear for me this and that... this is not right bro, we submit and search out knowledge.
It's true God could in one surah explained the Salah all in detail. However we don't ask why God does things. We submit.
You admit you don't know Quran in detail, you lack knowledge. We all do. However does his Messenger (pbuh) not know the book insight out? This is why we have to submit to the Messenger (pbuh) clarification of the Quran.
I admonish you to reconsider on how to approach the Sunnah of the Rasool (pbuh).
I understand you don't want to blindly follow people and their verdicts. This is fine. I don't do this either.
