I've been to somalia too and they learn Arabic in duggsi also the whole children television is dominated by Arabic translated shows. So they all speak Arabic to some extent just not in everyday conversation of courseI been back home up north and nobody speaks arabic stop the lies warya. Even dugsi students dont learn to speak arabic.
The language of the quran fyi is classical arabic, which is incomprehensible with modern standard arabic (what arabs speak today).
You need to calm down with the arab bootyclapping, we have our language and dhaqan unless you wish to be considered an aswad cabeed with no native language like sudani people.
