عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام )
قَالَ إِنَّ الشَّيْطَانَ أَشَدَّ مَا يَهُمُّ بِالْإِنْسَانِ إِذَا كَانَ وَحْدَهُ فَلَا تَبِيتَنَّ وَحْدَكَ وَ لَا تُسَافِرَنَّ وَحْدَكَ .
9. Ali ibn Ibrahim has narrated from his father from ibn abu ‘ Umayr from Hammad from al-Halabiy who has said the following:
“Abu ‘Abd Allah 
, has said, ‘Satan is the strongest against man when he is alone, thus one must not sleep alone or travel alone.’”
