Dawood wrote here that:
“Revelations not fully captured in the Quran were meant for prophet himself, teaching him, for example, how to read/write, how to pray, what are correct manasiks to be followed, etc., else he (prophet) could not have fully followed the Quran.”
Dawood, you wrote here that the Messenger received revelation outside of the Quran to make sense of what you do that is not in the Quran and now you claim that we are deluded with extra Quranic notions!
You wrote that manasiks are not in Quran and taught to the Messenger via this extra ‘revelation’, now you claim “Creed of Ibrahim and its related rites are well attested within the Quran”.
You made the claim that the Messenger could not fully follow the Quran without this extra ‘reveletion’ so you have proved that you do not accept the Quran as fully detailed and complete for what Allah wants us to do.
You have created a new religion called 'Followers of the Creed of Abraham'!
