٥٥- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنْ زَكَرِيَّا الْخَزَّازِ عَنْ يَحْيَى الْحَذَّاءِ قَالَ قُلْتُ لأبِي الْحَسَنِ (عَلَيْهِ السَّلام) رُبَّمَا اشْتَرَيْتُ الشَّيْ‏ءَ بِحَضْرَةِ أَبِي فَأَرَى مِنْهُ مَا أَغْتَمُّ بِهِ فَقَالَ تَنَكَّبْهُ وَلا تَشْتَرِ بِحَضْرَتِهِ فَإِذَا كَانَ لَكَ عَلَى رَجُلٍ حَقٌّ فَقُلْ لَهُ فَلْيَكْتُبْ وَكَتَبَ فُلانُ بْنُ فُلانٍ بِخَطِّهِ وَأَشْهَدَ اللهَ عَلَى نَفْسِهِ وَكَفَى بِاللهِ شَهِيداً فَإِنَّهُ يُقْضَى فِي حَيَاتِهِ أَوْ بَعْدَ وَفَاتِهِ.
55. A number of our people have narrated from Sahl ibn Ziyad from Ya’qub Yazid from Zakariya’ al-Khazzaz from Yahya al-Hadhdha’ who has said the following: “I once said to abu al-Hassan ‘Alayhi al-Salam, ‘I may buy certain things in the presence of my father and I see certain things in him that make me depressed.’ He (the Imam) said, ‘Avoid buying in his presence. When you have a right on a man say to him, “Write down, ‘So and so has written in his handwriting, assigning Allah as witness upon himself and Allah is sufficient witness.’” He will certainly pay in his life time or after his death.’”
