[Machine] The Messenger of Allah ﷺ said, "If there are three people traveling, they should appoint a leader." Nafi' said, "So I said to Abu Salamah, 'Are you our leader?'" 10350 Abu Ali al-Roudabari informed us, and Abu Bakr Muhammad ibn Bakr narrated to us, and Abu Dawud narrated to us, and Ali ibn Bahar narrated to us, and Hatim ibn Ismail narrated to us, and Muhammad ibn 'Ajlan mentioned it to us in a similar way, except that he said, 'If there are three of them...'"  

قَالَ رَسُولُ اللهِ ﷺ إِذَا كَانَ ثَلَاثَةٌ فِي سَفَرٍ فَلْيُؤَمِّرُوا أَحَدَهُمْ قَالَ نَافِعٌ فَقُلْتُ لِأَبِي سَلَمَةَ أَنْتَ أَمِيرُنَا 10350 وَأَخْبَرَنَا أَبُو عَلِيٍّ الرُّوذْبَارِيُّ أنا أَبُو بَكْرٍ مُحَمَّدُ بْنُ بَكْرٍ ثنا أَبُو دَاوُدَ ثنا عَلِيُّ بْنُ بَحْرٍ ثنا حَاتِمُ بْنُ إِسْمَاعِيلَ ثنا مُحَمَّدُ بْنُ عَجْلَانَ فَذَكَرَهُ بِمِثْلِهِ إِلَّا أَنَّهُ قَالَ إِذَا كَانُوا ثَلَاثَةً  

The Prophet ﷺ said: When three are on a journey, they should appoint one of them as their commander. (Using translation from Abū Dāʾūd 2608)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا خَرَجَ ثَلَاثَةٌ مِنْ سَفَرٍ فَلْيُؤَمِّرُوا أَحَدَهُمْ
