6ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ إِسْمَاعِيلَ عَنْ عَبْدِ الله بْنِ وَاصِلٍ عَنْ عَبْدِ الله بْنِ سِنَانٍ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيهِ السَّلام) لا تَثِقْ بِأَخِيكَ كُلَّ الثِّقَةِ فَإِنَّ صِرْعَةَ الإسْتِرْسَالِ لَنْ تُسْتَقَالَ.
6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn Isma’il from ‘Abd Allah ibn Wasil from ‘Abd Allah ibn Sinan who has said the following: “Abu ‘Abd Allah 
has said, ‘Do not trust your brother (friend) in totality; a sudden fall of attachment is never repairable.’”
