What is the meaning of the saying of the Prophet (peace and blessings be upon him): “The one traveler is a devil, the two travelers are two devils, and the three are a caravan”?

Question:
Our Shaykh, may Allah preserve you, what is the meaning of the saying of the Prophet (peace and blessings be upon him): “The one traveler is a devil, the two travelers are two devils, and the three are a caravan”?

Answer:
It is clear that this contains a prohibition against a person traveling alone, because he is exposed to dangers, exposed to illness, exposed to enemies, exposed to the breakdown of the car, or the breakdown of the mount he is riding. He may be exposed to destruction if he is alone, exposed to wild beasts, he is in danger. Traveling involves danger. So a person should not travel alone, because this is throwing oneself into destruction.
And the two travelers are two devils, because if the two quarreled and fought and struck each other, no one would be there to rescue them. Perhaps one of them would kill the other or harm him. And the three are a caravan; the three and more than three, this is a caravan. If a fight or disagreement occurs among them, who would rescue them and who would intervene between them and harm? So there is a recommendation that a person travel with a group, and not travel alone, and not travel with just one other person.
