٦- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ وَمُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ جَمِيعاً عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ هِشَامِ بْنِ الْحَكَمِ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ إِذَا قَالَ لَكَ الرَّجُلُ اشْتَرِ لِي فَلا تُعْطِهِ مِنْ عِنْدِكَ وَإِنْ كَانَ الَّذِي عِنْدَكَ خَيْراً مِنْهُ.
