Firstly congratulations for finding Satan in such an environment, you should feel proud.
Secondly under no circumstances give even the slightest impression to anybody EVER that your a Satanist, Iran is perhaps the most dangerous country in the world to be a Satanist, I would say make absolutely no physical altar or sigil or spiritually related anything in case you get caught to everyone you know simply pretend your a muslim, the Gods understand your predicament so be safe and secretive above all else, and in my opinion in Iran you should want to consider faking being a muslim for your own safety until you can leave to a safer country, normally I am very opposed to immigration but for a fellow Satanist in such an environment I would recommend it.
Your only interaction with learning Satanism should be digital and you must always remember to use either the tor browser or delete your browsing history after each session preferably both.
To answer your question the enemies rituals and instruments such as the quran have no effect whatsoever, dont worry about it at all, they are fake devoid of real power like that of our Gods, you could stand in a mosque do every prayer and it would barely affect you.
And you can always use the AskSatan service as you have for further help, this is literally its number one most important use.
Be secret, keep Satans covenant close to your heart and share it with none, all the resources you need are on Joy of Satan browse it using the torbrowser in order to avoid your government spying on you.
