Is this group, which uses people's belongings without permission, communicates only with its members, and rejects natural sciences on the grounds that God knows everything, on the straight path?

The aforementioned group is aberrant and misguided in its ideas, beliefs, and dealings. It is lenient in encroaching upon people's property without their permission, which is an injustice forbidden by Allah and His Messenger, for property is inviolable except with the owner's willing consent. Their extremism is also evident in their refusal to touch or speak with those outside their sect, and they hinder contemplation of the universe and forbid scientific inquiry, whereas Islam calls for reflection on the creation of the heavens and the earth. Such ideas spread in ignorant societies, and it is obligatory to advise this sect and invite them to the truth, and to warn people against their falsehood.
