yeah I suppose all the arabs from al Andalus to Uzbekistan were pure hijazi bedouins while the local populations never got arabized and became clients of arab tribes nor played any role in Science. The genius of Arabs can only express itself outside their homeland subhanallahYes ?
If the we have the evidence of the names of those people also their tribes then your claim is nothing but a lie .
Ain’ there a book of Islamic scientists their names and tribes ?
