Through his labels, he promoted hip hop musicians such as SSIO, Schwesta Ewa, Kalim, Eno, Shindy, and Sero el Mero.

In addition to his musical activities, Xatar expanded his entrepreneurial work with the fast food company Haval Grill, the hookah lounge Bar Noon, the tobacco brand Orijinal and jewelry and clothing design for Massari.

[5] At the end of the 1990s Hajabi began using the pseudonym Xatar, the Persian (Farsi) term for "danger", to rap and produce beats in the recording room of a youth center.

[5] In addition to his label colleagues Samy and SSIO, it also features guest contributions from La Honda, Azad, Jetsett Mehmet, Jamila and Jalaal.

[8] Less than a year after its release, Xatar's debut album was indexed by the Bundesprüfstelle für jugendgefährdende Medien ("German Federal Review Board for Media Harmful to Minors").

The album was completed and supplemented by guest contributions from rappers such as Farid Bang, Nate57, Celo & Abdi, Capo and Eko Fresh and released on his label in April 2012.

415, Alles oder Nix Records also released the albums Spezial Material and BB.UM.SS.N by SSIO, Realität by Schwesta Ewa and Sechs Kronen by Kalim during Xatar's imprisonment.

[20] At the same time he started the production of his third album, for which he was again able to attract a number of well-known guests such as SSIO, Haftbefehl, Schwesta Ewa, Olexesh, Kalim, Samy and Teesy.

[23] On 12 October 2015, he published his autobiography Alles oder Nix: Bei uns sagt man, die Welt gehört dir through riva Verlag.

[31][32] In May 2016, Xatar and Haftbefehl announced their joint album Der Holland Job with a promotion campaign as part of the television show Studio Amani and the subsequent removal of their social media profiles.

[37][38][39][40] In November Xatar dissolved his second label, causing the rappers Eno, Yonii, Sylabil Spill, Ajé, Joao Michel Diau, Dollar Euro Yen and Levo to lose their contracts.

[44][45] Xatar was commissioned to compile a sampler for the German gangster movie Nur Gott kann ich richten with Moritz Bleibtreu, produced by Özgür Yıldırım.

The reporter Ilhan Coşkun interviewed a person appearing under the pseudonym Kai, who claimed to influence the charts on behalf of managers.

[79] The following albums released through the distribution channels of major labels, Der Holland Job and Alles oder Nix II, also reached number 1 in the charts.

[83] At the same time as his personal commercial breakthrough, Xatar was also able to celebrate his first successes as label manager of Alles oder Nix Records.

[93] For the tenth anniversary of Alles oder Nix Records Michael Rubach from Hiphop.de looked back on the development of Xatar and his label.

With their "no-frills street rap", they have set themselves apart from the "trends or stylistic twists of the time," which "had their roots above all in Berlin's underground and the boys from Düsseldorf with their powerful word play".

In addition, Xatar used terms such as "Baba" "long before Haftbefehl and other Frankfurters of the generation after Azad had made the mixed-cultural slang mainstream-friendly".

According to David Maurer, Xatar, who rolls "back into the game in an armored jeep like a mighty godfather dominating everything", embraces "a powerful aura".

In terms of content, however, "even after a few runs" it became apparent that "the tracks about his life before, during and after prison don't have a particularly long half-life despite a good starting position".

Nevertheless, the Bonn artist showed "that a good album doesn't necessarily require complex rhyme structures and intricate storytelling".

[95] Holger Grevenbrock praised the "dynamics of fast and slow parts" with regard to Der Holland Job, which "ensure a constant tension".

While Xatar "rather mimes the classic gangster", who proclaims that "negotiating is a matter for the boss", Haftbefehl "is his completely over-excited sidekick à la Robert De Niro in ‚Mean Streets'.

Although "strong lead tracks like 'Iz Da' or 'Original' are missing", Xatar shows his "reflective side" in the honest song Schwesterherz.

Tobias Rapp of Spiegel praised Alles oder Nix: Bei uns sagt man, die Welt gehört dir.

With Platz ins Geschäft, Eine Geschichte 1, Skit, Guck wie dein Herz klopft, Lauf weg, §31 and B.O.X.

From the point of view of the Review Board, Xatar presents the "exercise of violence as worthy of imitation" and a "violent assertion of one's own interests as an alternativeless concept of action".

The "rather descriptive, partly socially critical texts of the other songs are not able to create an overall context that would be suitable to absorb the statements relevant to indexing and give them a different meaning.

Since the men involved were associated with Xatar and the injured man with the musician KC Rebell, some tabloid media spoke of a "rapper war".

There had been public disputes between the two hip-hop musicians some time before, after Xatar had claimed that KC Rebell had wanted to join Alles or Nix Records a year earlier.
