There are lots of reports about partial formatting affecting kerning, glyph joining, mark positioning. They are all caused by the same underlying issue. They should all be duplicates of bug 61444.

*** This bug has been marked as a duplicate of bug 61444 ***

It should be noted that:

1. Changing the color of the entire text to "automatic" removes some, but not all, of the differences in rendering.

2. Removing all direct formatting results in the word Allah with two shadda's rendered, one above and one below the superscript-aleef. Khaled, shall I file that as a separate bug?
