The earliest inscriptions of clear matured forms for Musnad scripts is from the time period, around the 9th to10th centuries BCE. Musnad and Phoenician had clear common roots, shapes and maturity period.
 
Many articles and books repeate the conclusions of western scholars of the nineteenth century, based on a handful of inscriptions, about a Arab Nabataean transformation to Arabic script. Few, like Mādūn, challenged this notion with serious and interesting analysis and reasoning. He speculated with illustrative details about a possible transformation of older Arabic Musnad shapes to modern ones, instead. Today there are many books and articles, disagreeing with the Aramaic Nabataean origin theory without offering a solid alternative theory.

For a long time, early Arabic was torn between its Musnad roots and the more mature Aramaic scripts around it. It may have had incorporated several Nabataean shapes, but it is hard to definitely claim it was a transformed Nabataean script based on a couple of inscriptions distantly resembling Arabic, especially since Aramaic Nabataean and Musnad have similar shape roots.
