١ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ الْعَلاءِ بْنِ الْفُضَيْلِ وَحَمَّادِ بْنِ عُثْمَانَ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) يَقُولُ انْظُرْ قَلْبَكَ فَإِذَا أَنْكَرَ صَاحِبَكَ فَإِنَّ أَحَدَكُمَا قَدْ أَحْدَثَ.
1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Muhammad ibn Sinan from al-‘Ala’ ibn al-Fudayl and Hammad ibn ‘Uthman who has said the following: “I heard Abu ‘Abdillah  saying, ‘Look in your heart, if it dislikes your friend, one of you has done something (wrong).”’
