Narrated 'Amr bin Shu'aib:

From his father, from his grandfather that the Messenger of Allah (ﷺ) said: "The (lone) rider is a Shaitan, and two raiders are two Shaitan. Three is a travelling party.

[Abu 'Eisa said:] The Hadith of Ibn 'Umar (no, 1673) is Hasan Sahih. We do not know of it except from this route ; as a narration of 'Asim. And he is Ibn Muhammad bin Zaid bin 'Abdullah bin 'Umar.

Muhammad said: "He is trustworthy, truthful. And 'Asim bin 'Umar Al-'Umari is weak in Hadith, I do not report anything from him." The Hadith of 'Abdullah bin 'Amr (no. 1674) is better.
