Syed Bhai, Creed of Ibrahim and its related rites are well attested within the Quran. Those who deny these rites, their arguments are the weakest and easily rejected via same verses they bring to support their claims, provided they stay true to grammar and lexicons, etc. In my view, the problem is within oneself, the desire to see the Quran and its interpretation through one's extra-quranic thoughts, ideas, and notions. They come up with some questions like this: "physical rituals have no place in Quran" or "God could not do this and that..or God could not mean this and that....etc." Then their second step is to jump from this argument to "re-defining" well defined and understood words and terminologies in Quran. In doing so, they will go through all sorts of hoops, neglecting the language itself upon which they base their arguments. It is a self-delusional cycle, they can never come out until unless they let their extra-quranic notions go and truthfully let the quran speak for itself. I wish I had time at my disposal, I could shred their arguments in pieces via Quran, don't need hadeeth or anything else.
