Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 16
وَ قَالَ أَبُو اَلْحَسَنِ مُوسَى بْنُ جَعْفَرٍ عَلَيْهِمَا اَلسَّلاَمُ: فِي وَصِيَّةِ رَسُولِ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ لِعَلِيٍّ عَلَيْهِ اَلسَّلاَمُ «لاَ تَخْرُجْ فِي سَفَرٍ وَحْدَكَ فَإِنَّ اَلشَّيْطَانَ مَعَ اَلْوَاحِدِ وَ هُوَ مِنَ اَلاِثْنَيْنِ أَبْعَدُ يَا عَلِيُّ إِنَّ اَلرَّجُلَ إِذَا سَافَرَ وَحْدَهُ فَهُوَ غَاوٍ وَ اَلاِثْنَانِ غَاوِيَانِ وَ اَلثَّلاَثَةُ نَفَرٌ وَ رَوَى بَعْضُهُمْ سَفْرٌ ».
Abu al-Hasan Imam Musa ibn Jafar Al-Kadhim عليه السلام said, in the will of the Messenger of Allah سبحانه وتعالى (peace and blessings of Allah سبحانه وتعالى be upon him and his family) to Imam Ali عليه السلام: "Do not set out on a journey alone, for Satan is with one person, and he is farther away from two. O Ali, when a man travels alone, he is misguided; two are misguided; but three are a group." Some narrators reported: "three is a journey."
