The Book of Etiquette of Traveling
The Desirability of undertaking a Journey in a Group and appointing a Leader
عَنِ ابْنِ عُمَرَ رَضِيَ اللَّه عَنْهُمَا قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ : "لَوْ أَنَّ النَّاسَ يَعْلَمُونَ من الْوَحْدَةِ مَا أَعْلَمُ مَا سَارَ رَاكِبٌ بِلَيْلٍ وَحْدَهُ” ((رَوَاهُ الْبُخَارِيُّ)).
Ibn 'Umar (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) said, "Were people to know of what I know about the dangers of travelling alone, no rider would travel alone at night." [Al-Bukhari].
