The hadith are from Muhammad (SAW). It is a falsehood to make such claims as to the reverse. The Qur’an is revealed, but before the Qur’an came the man upon whom the Qur’an was revealed was sent. You are undermining the prophet (SAW) by saying that all he is a tape player for God (Audzubillah) he was the master of the true understanding of the Word of God and his words are our teachings on how best to understand the verses. You do away with that aspect and then you will have to rely on your own interpretations which are subject to the norms of your own abilities and experiences.
The Qur’an never says that ablution consists of only four steps, if it does then please show where this limiting expression exists. You need to understand what context, elaboration actually means and at the same time you also need to do a course in logic or semantics as you clearly confuse the idea of contextualisation with contradiction on a regular basis.
