polyglossia and Latin enumerate problem

Question

I use polyglossia package and when I try to enumerate in this way ( 6a,6b,6c,,, ) it changes to arabic alphabet. how can I write it in the way I want it (6a,6b,6c).

\documentclass[a5paper]{article}
\newcommand{\subscript}[2]{$#1 _ #2$}
\usepackage{amsfonts}
\usepackage{polyglossia}
\usepackage[utf8]{inputenc}
\usepackage{enumitem}
\setdefaultlanguage[numerals=maghrib]{arabic}
\setotherlanguage{english}
\newfontfamily\arabicfont[Script=Arabic,Scale=1.2]{Scheherazade}
\begin{document}
\begin{enumerate}[label={6}\Alph*]
\item خوایه‌ وه‌ته‌ن    
\item  چه‌ند دڵگیر و شیرینه‌
\end{enumerate}

\end{document}

Remark:- I found this answer to my question, but now if I write kurdish language after \item it will not shown, only Latin text will be appear which is again a problem.

Answer 1

To recover the definition of \@alph you can add

\appto\arabic@numbers{%
   \let\@alph\@origalph%
   \let\@Alph\@origAlph%
   }

Code

\documentclass[a5paper]{article}
\newcommand{\subscript}[2]{$#1 _ #2$}
\usepackage{amsfonts}
\usepackage{polyglossia}
\usepackage{enumitem}
\setdefaultlanguage[numerals=maghrib]{arabic}
\setotherlanguage{english}
\newfontfamily\arabicfont[Script=Arabic,Scale=1.2]{Scheherazade}

\makeatletter
\appto\arabic@numbers{%
   \let\@alph\@origalph%
   \let\@Alph\@origAlph%
   }
\makeatother

\begin{document}
\begin{enumerate}[label={6}\alph*]
\item خوایه‌ وه‌ته‌ن    
\item  چه‌ند دڵگیر و شیرینه‌
\end{enumerate}

\end{document}
