actually arabxetex only ask for amsmath, it will not load it if has
been already loaded.

The test in mathspec is logical wrong. It hacks \RequirePackage (not
a good idea anyway at my opinion) to throw an error if its argument
is "amsmath" but it doesn't disable this hack if amsmath has been
loaded correctly before mathspac.

mathspec should better test at the begin of the document if amsmath
has been loaded after mathspec and then throw an error.

You can disable the wrong test like this:

\documentclass{article}
\usepackage{amsmath}
\usepackage{mathspec}
\makeatletter
%\let\RequirePackage\original at RequirePackage %uncomment
\makeatother
\usepackage{arabxetex}


\begin{document}
abc
\end{document}
