← Previous Hadith That Ibn Juraij commented on Allah's saying: Obey Allah and obey the Messenger, and those in authority among you. He said: "Abdullah bin Hudhafah bin Qais bin 'Adi As-Sahmi was sent by the Messenger of Allah (ﷺ) over a military expedition. I was informed of that by Ya'la bin Muslim, from Sa'eed bin Jubair, from Ibn 'Abbas.

This Hadith is Hasan Sahih Gharib. We do not know if it except as a narration of Ibn Juraij.

Jami` at-Tirmidhi Book 23, Hadith 3 Next Hadith → 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.

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.
