Yes, emacs -Q is picking this font:

xft:-unknown-Metal-normal-normal-normal-*-13-*-*-*-*-0-iso10646-1

from debian package ttf-arabeyes:

/usr/share/fonts/truetype/ttf-arabeyes/ae_Metal.ttf

and "emacs" this font (in accord with my default font customisation):

xft:-unknown-DejaVu Sans Mono-normal-normal-normal-*-15-*-*-*-m-0-iso10646-1


Actually, I suspect (not that I know arabic) both cases are displaying 
it incorrectly (not composed), but it looks particularly off with the 
former, with the character cell for the character taking up half the 
screen.  This might be partially a problem with the font in question.

(I'm going through old bug reports that have unfortunately gotten no
attention yet.)

I tried reproducing this in Emacs 27, but as far as I can tell, the
Arabic text shows up composed for me (emacs -Q is using "Ubuntu Mono")
on my GNU/Linux system.

Are you still seeing this problem, or has it been fixed in the
intervening years?

FWIW, I cannot see any problems, and am almost positive they were
either fixed or were due to a faulty font.
