You can doubt. No problem with that.<quoted text>
I doubt if the pagans circumcised. The Jews of Yathrib would but not those pagans. The practice of circumcision was borrowed from the Jews.
The Sunni explanation is that there were 3 possiblities: 1) He was born circumcised 2) Abu Talib did the circumcision 3) Gabriel performed the circumcion.....allah knows best!!!
The practice of circumcision did NOT come from the Jews. They appeared very late on the scene.
They also followed the practice as commanded by Moses, who was ordered to circumcise all. And at that time, those folks, who lost their foreskins happily, were the Hebrews and many others.
The practice was initiated by Abraham and was followed by Ismael, Issac, Jacob, Joseph, the patriarchs, who WERE NOT Jews.
The generations of Issac and Ismael were getting their foreskins chopped gladly, without any hesitation. So, circumcision was nothing new. That is why you do not see an instruction in Qur'aan to Muslims, to get circumcised.
I had asked you to quote ahaadith on circumcision. You have not quoted any. Could not find, is it?
That prophet was born circumcised, that Abu Talib did the circumcision and that Gabriel did it, IS all rubbish and absurd! Both the Sunnis and the Shias conjecture.
