This edition/printing credits Sahar Jabr Mahmoud as the translator; probably erroneously. SJM most likely revised Rajaa Abdullah's translation. The mistake was corrected in the following editions/prints
"printing" here is referred to as "edition" in the book's front matter. It appears that they publisher did not distinguish between different editions and different printings. Thus the print number here is contiguous to the previous 'edition'
Harry Potter and the Philosopher's Stone
"Translator" is very confusing with the Arabic translation. The first 2002 edition of the book lists Rajaa Abdulla; later editions have a modified text and credits Sahar Jabr Mahmoud. And then Rajaa Abdulla is credited as translator with Sahar Jabr Mahmoud as "Reviewer/Editor".
Analyzing the text, it is clear they are all the same modified translation.
