I received a comment from one of moderators:
You keep asking for some sort of Islam.SE-specific policy, but there is no such thing. Check out meta.stackexchange.com/q/58842/132874 if you want a relevant meta discussion. source
It is amazing for me to hear this site has no specific policy.
I think it has contradiction with this meta post by user:
Policy Discussions of Islam.SE
And also with this post with the same user:
https://islam.meta.stackexchange.com/a/1036/67
Some of policies are enforces by SE Inc. Indeed I am not talking about them. I talk about others that Islam site community itself should decide about them.
There are two options:
1- Everything depend on moderators. they search and find some meta posts from all over the SE network and take action based on them and their own opinion and interpretation.
2- Islam site have a clear set of policies. not in form a jungle of meta QAs, but something like developed version of current help center that can be updated by time. in this case moderators can take moderation actions (like deleting of closing posts) only according to one of per-defined and clear Islam site policies.
Here are some similar discussions on other sites of SE network:
How is consensus determined on Meta sites?
Please note this question does not mean deleting all help center and all past useful knowledge for managing this site. but means the part of policies that can not be used from past knowledge according to nature of Islam as a religion. perhaps 90% of site policy can be taken from past useful knowledge. but still 10% is needed to be made specifically for this site. I am talking about that 10%.
