The Book of Etiquette of Traveling
The Desirability of undertaking a Journey in a Group and appointing a Leader
وَعَنْ أَبِي سَعِيدٍ وَأَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُمَا قَالَا: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : “إِذَا خَرَجَ ثَلاَثَةٌ فِي سَفَرٍ فليأمروا أحدهم" حَدِيث حَسَن، ((رَوَاهُ أَبُو دَاوُدَ بِإِسْنَادٍ حَسَنٍ)).
Abu Sa'id Al-Khudri and Abu Hurairah (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) said, "When three persons set out on a journey, they should appoint one of them as their leader." [Abu Dawud].
