I knew this will be your answer and I am waiting for that, because now you are arguing like a politician or lawyer not as a scholar. You never answer a direct question rather always deflect the question with another question – hallmark of a lawyer.
On what basis you are confining “Creed of Ibrahim” to geographical limit of Mecca only?
Why only the practices of people of Mecca or Arabia can only be called as “creed of Ibrahim”?
Who told you that progeny of Prophet Ibrahim never left the Arabian region and never settled in other region of world along with their customs/rituals/practices?
For the sake of your information, it is well known fact in India that the great Ram – the most venerated King of India, belongs to “Ikshwakoo” lineage. “Ikshawakoo” is nothing but “Issac/Ishaaq” in Sanskrit language, according to many historians.
So if any Hindu claims that their practices/rituals are also part of “creed of Ibrahim’ and are being followed through unbroken chain of continuity from last 4000 or so years, what will be your basis of denying their claim? Will you refute their claim just because it is not a “well established fact” according to your opinion? Or now they don’t speak Semitic languages they cannot be from lineage of Prophet Ibrahim? or any other reason?
Dawood Bhai, “Creed of Ibrahim” is nothing but Pure Monotheism as elaborated in Quran which I understood from reading it. You are mixing “creed of Ibrahim” with extraneous sources not found in Quran just to defend your stand and ego.
Regarding answers to my questions, I just look into Quran, unlike you I don’t bother to look into history, community and region, for I believe in what God has said in Quran that His book is complete and He missed out nothing.
