Ideas in the Najdorf Sicilian as Black

How would White get a Maroczy Bind exactly ?

Not in the Najdorf, sure. But White could play the Chekhover before Black reaches a Najdorf setup - perhaps that's what the OP is asking about.

For example:

Yes, but the 3... Nf6 move order cuts that option out (as well as the Prins).

Actually, it is possible. Back in 2021, I was playing the lines from Steamrolling the Sicilian by Sergey Kasparov (NOT Garry).

After 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 and now 5.f3 instead of 5.Nc3, known as the Prins Variation, and now while the normal moves are 5...e5, 5...e6, and 5...Nc6, I have seen Najdorf players play 5...a6, and now 6.c4 is a Maroczy Bind, and so yes, even a Najdorf player could have to face the Maroczy Bind.

Curiously, it is possible for the Prins to directly transpose to the Accelerated Dragon, a 2...Nc6 Sicilian. Not something your 2...d6-Sicilian player would typically be aiming for.

The anti-chekhover move order also prevents the Prins. But you can get a maroczy-bind type position regardless via the Moscow. But very few people actually play the anti-chekhover so I wouldn't really design a white repertoire to avoid that anyway, and you can just play the unique lines there anyway if you're really worried about it.

@playchessordie19 I don't play the Najdorf but I can give you advice on how to deal with the anti-sicilians on your way up to the Najdorf. 
- the anti-checkhover (3... Nf6) is a good line, I would recommend that. You do need to know the theory to take advantage of the surprise factor 
- against the alapin my personal favorite is 2... d5 > 3... Nf6 
- I'd recommend just accepting the Smith Morra and playing the a6/e6/Nc6 > b5 setup
- against the delayed alapin just play Nf6 > g6 / Bg7 / O-O. If you play this right you can prevent white from playing d4 and the game is just equal, it's an easy line 
- against the closed you probably want to play 2... a6 since you're going for the Najdorf. Don't play 2... d6, it's terrible against the Grand Prix and the fiancetto.
- against the Moscow I prefer 3... Bd7 over 3... Nd7. Bd7 is a much tighter, more compact line, since it's traded off a piece already. The 3... Nd7 line can get very huge. Compactness makes things easier for you, you don't see the Moscow too often.

That's great ideas for me to digest. I've been trying to find other lines besides counter attacking in the center and due to the mixed results I have with various replies a Black and a lack of good books to read, I'm going to start looking at these lines and some of the videos once I get my vinyl board from Amazon.

That Bd7 idea against the Moscow is actually one I'm trying after a video from Remote Chess Academy that I saw. White has so many ways to go wrong playing "normal" moves that it's worth a go sometimes.
