why I can't write an Abstract with 3 languages Arabic, french and English

Question

I'm writing my master thesis with Latex, so I'm trying to write an abstract with arabic, french and english, I'm using pdfLatex engine, here's the main.tex :

\documentclass[fontsize=12pt,parskip=half,appendixprefix,headsepline,numbers=noenddot, openany]{scrbook}

\input{Structure_memoire}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\include{frontmatter/page de garde}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%\newcommand{\disableopenany}{%
%   \@openrighttrue%
%}                                                               document
%\makeatother
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
\bibliographystyle{unsrt}
\captionsetup{labelfont=sc}
\begin{spacing}{1}
\pagestyle{empty}
\frontmatter
\maketitle

\end{spacing}
\end{document}

and this is all the pachages that I'm using:

\usepackage{float} %Pour dire que les "tables" sont des "tableaux" \usepackage[tablename=Tableau]{caption} \usepackage{array} \usepackage{minitoc} \usepackage{shorttoc} \usepackage[dvipsnames,table,xcdraw]{xcolor} \usepackage{tikz} \usepackage{framed} \usepackage{lettrine} \usepackage[inline]{enumitem} \usepackage{arabtex} \usepackage[utf8]{inputenc} \usepackage[arabic]{babel}

\usepackage{subcaption} \usepackage{setspace} \usepackage[ruled,linesnumbered,lined,boxed,commentsnumbered]{algorithm2e} \usepackage[kerning=true,spacing=true,tracking=true]{microtype} \usepackage{enumitem} \usepackage{pdfpages} \usepackage{etoolbox}

so any solutions please ?

Answer 1

scrbook doesn't have an abstract environment. So you could define your own one, like

\newenvironment{abstract}[1] % title
{%
  \renewcommand\raggedsection{\centering}%
  \section*{#1}%
  \begin{quote}%
}
{\end{quote}}


\begin{document}
\frontmatter

\begin{abstract}{Résumé}
  French abstract
\end{abstract}

\begin{abstract}{Abstract}
  English abstract
\end{abstract}

% Don't know Arabic

\mainmatter

\chapter{First chapter}
