The ruling on a murderer seeking refuge with another tribe to request protection

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Is it permissible to cite the fact that some of the Companions sought the protection of some polytheists as evidence for what some tribes do now, where if one of them kills another person, he takes his family and they enter the protection of another tribe, fearing for their lives from the family of the victim?

Answer:
No. It has been reported to us that when this happens, they go to another tribe to prevent them [the victim's family] from killing the murderer immediately, until the judge rules between them, so that they do not hasten to kill the murderer until the ruling is issued regarding him, the Sharia ruling. This is what we have come to know through the questions that reach us: that he seeks refuge with another tribe to protect him from the harm of that tribe until the Sharia ruling is issued against him.
