١ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ مَا مِنْ قَلْبٍ إِلا وَلَهُ أُذُنَانِ عَلَى إِحْدَاهُمَا مَلَكٌ مُرْشِدٌ وَعَلَى الأخْرَى شَيْطَانٌ مُفْتِنٌ هَذَا يَأْمُرُهُ وَهَذَا يَزْجُرُهُ الشَّيْطَانُ يَأْمُرُهُ بِالْمَعَاصِي وَالْمَلَكُ يَزْجُرُهُ عَنْهَا وَهُوَ قَوْلُ الله عَزَّ وَجَلَّ عَنِ الْيَمِينِ وَعَنِ الشِّمالِ قَعِيدٌ ما يَلْفِظُ مِنْ قَوْلٍ إِلا لَدَيْهِ رَقِيبٌ عَتِيدٌ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from Abu ‘Abdillah  who has said the following: “There is no heart without two ears. On one of them there is an angel who provides guidance and on the other there is a Satan (devil) who induces temptation. This one commands him and that one prohibits him. Satan commands him to disobey and the angel prohibits him from sins as it is mentioned in the words of Allah, the Most Majestic, the Most Holy, ‘. . . since the two scribes are sitting on each of his shoulders, he does not utter a word that is not recorded immediately by the watchful scribes.’” (50:17).
