Who Is The Quran Addressing?
Just like existence of God, praying to that God is also an innate need and a universal truth by extension. So when God tells a way to pray, why use our own imagination to come up with new methods of praying? When we know that this is the way God wanted them to pray, so this should’ve been the way God wanted us to pray and the same practice has been transmitted to us through Sunnah.
