Quran says Messenger cannot add anything to Deen of Allah, so this is ancestor worship, even when applied to Messenger, and not following Allah as per Quran.”
I asked you earlier, show me what people do in Nimaz today is from hadeeth? You could not or you did not. It is a huge misunderstanding among many quran-only Muslims that today’s salat is somehow derived from hadeeth.
Second, ancestor worship is a loaded word to paint things in black and white. When Quran asked prophet to “follow the creed of Ibrahim”, was God advocating to do ancestor worship? When prophet did follow the creed of Ibrahim, did he indulge in ancestor worship? You can answer these questions for yourself.
