Suspicious portals with content in Albanian have published an article claiming that it presents a membership booklet of the League of Communists – Movement for Yugoslavia, of former Kosovo Prime Minister Isa Mustafa.
After researching through the automated online fact-checking program "InVID", hibrid.info has managed to confirm that the booklet presented by these dubious portals is fake, precisely edited.
The presented notebook did not belong to Mustafa, but rather to the former Prime Minister of Croatia, Jadranka Kosor.
You can find the photo of the authentic passport of the former Prime Minister of Croatia. here.
So, the author of this article has interfered with the photo of Kosor's passport, removing the photo of the Croatian politician and replacing it with Mustafa's. This has also happened with the first and last names of the aforementioned persons. (see pictures below)

This article was also shared on the social network Facebook by the pages "Der Kosova Albaner" and "Specialja", which have collected a large number of comments and reactions in these posts. (see here and here)
It is true that Isa Mustafa was part of communism during his political career, as in 1984 he was engaged in the function of the head of the communist municipal government in Pristina, a function he held until 1988. (see here)
But, despite this, the booklet presented by the dubious portals does not belong to former Prime Minister Mustafa.

Suspicious portals have published the membership booklet of the League of Communists - Movement for Yugoslavia, which belonged to former Croatian Prime Minister Jadranka Kosor.
However, the author of this article has interfered with this booklet, removing Kosor's photograph, first and last name, and replacing them with those of Isa Mustafa.
After fact-checking, hybrid.info rates this article as "Fake News".
Reasoning:
The "Fake News" rating is given to media reports that are entirely the product of a medium that itself contains factually incorrect claims or information.
Content that is considered fake news can be reliably determined to have been created and distributed with the intent to misinform the public, i.e., to present a claim that is completely false as fact.
