It doesn't happen for me, with that page, either in Emacs 25.1.50 or
25.0.91.  The Arabic shaping does work for me.

Do you have the same problem with the Arabic text in the buffer
created by "C-h H"?

The screenshot you attached indicates that complex script display is
not working for some reason.  Since your Emacs is built with libotf
and libm17n, the problem might be in old versions of these, so perhaps
rebuild with newer ones?  Or maybe try a different font?
