Salaams,
I have a brief note to add as an advisory on a more precise date for the Omani Kattaras which I put more toward the end of the 8th Century A.D. since Oman adopted Islam in 630 A.D. however, it is the Ibadi sect we are concerned with and that only transpired in the early 8th Century AD.(about 710) Allowing for time to settle and inform the masses my estimate would be mid to late in the 8th C. My target date therefor is 751AD; Religion, tradition, swords and all.
751AD.
This date to be further supported in my next addition to the Forum expected later today.
