我有这个：
\documentclass[12pt]{arabbook}
%%%%%%%%%%% packages
\usepackage{fancyhdr}
\usepackage{arabtex}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{amsfonts}% R ensemble des nombres reels
\usepackage{graphicx}% ajouter des photos
\usepackage{pstricks}% pour dessiner

\hoffset= -1.5 cm%truecm %
\voffset= -1.5 cm%truecm %
%%%%%%%%%%
\pagestyle{fancy}
\renewcommand{\headrulewidth}{1.5pt}
\renewcommand{\footrulewidth}{1.5pt}
\renewcommand{\baselinestretch}{1.5}
% `dm Alt^skyl
\novocalize
% bdAyt Alw_tyqT
\rhead{\RL{Alf.sl Al'awl}}
\lhead{\RL{`nwAn Alf.sl}}
\begin{document}
\begin{arabtext}
\end{arabtext}
\end{document}
我想定义定理环境，得到“nzryT 1：...”
请问该怎么做？
谢谢

这是使用 xelatex 和包 arabxetex 的解决方案。
