Actually that “Islamic” attribute does not have much relation to being islamic in concept! (some how similar to “christian science monitor” that is not about christian news!). That simply means the institute is affiliated with some elements of power structure in Iran.
I just had a look into both Persian and English sections of the site, there are journals such as “Sufistic Literature (in Persian)” which might show the need for such SCI, there are ISI rated ones also in the list, such as “international journal of environmental research” but there also English and non-special-discipline journals with no other international ranking that are probably non-qualified scientific journals.
At the same time the list of top scientists impact-factor looks so politically influenced. Therefore I do not reject the possibility of “system tuning” for better serving individual’s interests.
