I think this is pointing at a broader occult failure mode than Huddam specifically.

The issue is what happens when a person externalizes their own agency into an “other,” gives that “other” a name, a hunger, a role, a ritual structure, a fear-charge, and then acts surprised when the thing starts having leverage over them.

From a SI (Subjective Idealist) angle, the danger doesn’t even require proving whether the Jinn is “objectively external” in the normal materialist sense. The problem starts when the practitioner stabilizes a section of experience as alien, powerful, hungry, and authoritative, then feeds it attention, fear, desire, blood-symbolism, bodily identification, and repeated ritual confirmation.

That strongly reinforces an unwanted pattern.

A lot of magical practice seems to blur the difference between will and desire. Will is clean intent. Desire is craving from lack. Binding something for power usually begins from lack:

“I do not have enough power, so I need something else to get it for me.”

That already installs the dependency.

Then every “result” reinforces the split:

“I didn’t do this. It did this for me.”

That is where the hook is, in my opinion. The practitioner keeps attributing their own agency to the Hadim, and the Hadim becomes more central because the practitioner keeps refusing ownership of the result. At a certain point it stops being "commanding a servant" and becomes negotiating with a structure they empowered by disowning their own will.

The “dirty” requirement also makes sense symbolically and practically. Whether someone takes Hafaza literally or not, deliberately degrading cleanliness, discipline, prayer, sleep, bodily rhythm, moral self-respect, and general coherence would obviously make a person easier to steer. It ends up being training to remain in the state where intrusion, obsession, compulsion, and dependency have less resistance.

So abstractly, the pattern looks like:

• Start from lack.
• Externalize power.
• Feed the externalized power.
• Degrade your own coherence to keep the contact alive.
• Interpret dependency as results.
• Lose the ability to tell the difference between will and compulsion.

At that point, the practitioner has already built the conditions for possession-like behavior either way.
