Is there evidence in the Prophet’s seclusion in the Cave of Hira for the permissibility of withdrawing from people for a period of time?

Question:
The Honorable Shaykh, may Allah grant you success, asks: Is it taken from the Prophet’s (peace and blessings be upon him) seclusion in the Cave of Hira and his withdrawal from people that it is prescribed to withdraw from people for a period of time and not mix with them except in congregations and gatherings? This is for the sake of reviewing people and staying away from verbal and practical trials?

Answer:
This is from the methodology of the Sufis, the seclusion they call it, and the withdrawal from people. This is among the religious innovations (bid'ah) of the Sufis. A person needs to mix with people. He needs to mix with people, enjoy their company, and proceed with them in his affairs. Then, if he has knowledge and the ability to teach and to enjoin good and forbid evil, it is not permissible for him to isolate himself at all.
As for if he is an ordinary person and ignorant, and there is danger in his mixing with people that he will be influenced by them, there is no harm in him staying away from them to some extent, but he does not cut himself off and isolate himself completely, rather he stays away from them to some extent and isolates himself from them to some extent. Yes.
