A misguided group
    says that people’s property is permissible for them, and they do not look at anyone
    except members of their own group
Question

                In indonesia there is some kind of society
      that they have a funny rules (very-very strict rules).The rules is they may use anyones property without asking because they
      said it was Allah's. They can only speak, touch, and look at others face if they were one
      society with them!The other rules is they don't believe in educational science that teachers
      gave to them. Examples: Gravitation in earth is not a physically matter, but it's a matter
      that we can not answer (and search for answer) for only Allah knows it.My question is: Is this society in Allahs way. This society is really
      disturbing us. So pleas kindly answer and reply.
Praise be to Allah.According to what was said in the question, this is a
    weird group whose ideas, beliefs and conduct are misguided. It is strange that you say
    they have strict rules, but they are so lenient with regard to other peoples
    property and overstep the limits by using peoples things without their permission.
    This is Zulm (wrongdoing, oppression), and Allaah says (interpretation of the meaning):
The way (of blame) is only against those who oppress men and
    rebel in the earth without justification; for such there will be a painful torment
    [al-Shooraa 42:42]
The Prophet 
 (peace and blessings of Allaah be upon him) said:
    The whole Muslim is sacred to another Muslim: his blood, his property and his
    honour (Narrated by Muslim, 4650). And he 
 (peace and
    blessings of Allaah be upon him) said: It is not permissible for a man to take any
    of his brothers property except with his agreement (narrated by Imaam
    Ahmad, 20180).
    The Creator and Lord of wealth is the One Who has
    forbidden the violation of the wealth which He has bestowed on people in this world and
    given them permission to possess it. So how can these people accept this corrupt
    justification for going against the rulings of Allaah? The fact that their deviation is
    extreme is abundantly clear from the fact that they do not touch or speak to anyone who is
    not a member of their group. I wonder how they can live among people if they are not even
    allowed to look at others!
Moreover, they have forbidden looking at the heavens and earth and
    finding out what Allaah has created in them, by forbidding scientific research and finding
    answers to questions about natural phenomena. But Allaah says (interpretation of the
    meanings):
Say: Travel in the land and see how (Allaah) originated
    the creation, and then Allaah will bring forth the creation of the Hereafter (i.e.
    resurrection after death). Verily, Allaah is Able to do all things
    [al-Ankaboot 28:20]
Say: Behold all that is in the heavens and the
    earth [Yoonus 10:101]
Do they not look at the camels, how they are created? And at the
    heaven, how it is raised? And at the mountains, how they are rooted (and fixed firm)?  And
    at the earth, how it is outspread? [al-Ghaashiyah 88:17-20]
And there are other texts which indicate that we should ponder the
    universe and find out about what Allaah has created.
Ideas such as those promoted by these people do not find acceptance
    except in an ignorant society and among foolish and simple-minded people who do not know
    the basics of Islam. We have to advise this misguided group and call them to the truth,
    whilst warning people against their falsehood. May Allaah protect us and you from
    confusion, innovation and misguidance. And Allaah is the Guide to the Straight path.
