If the problem comes and goes as you change fonts, then the problem is not with Emacs, it is with the fonts you are using: they should support Arabic shaping. Emacs by default chooses suitable fonts for the Arabic script, but if you force Emacs to use certain font, you can disrupt the automatic font selection algorithm and choose a font that doesn't support Arabic shaping. The problems reported earlier existed with any font, and didn't disappear when a font was changed.
