1645 - وَ سَأَلَ عُبَيْدُ اَللَّهِ بْنُ عَلِيٍّ اَلْحَلَبِيُّ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ : عَنِ اَلْكَنْزِ كَمْ فِيهِ فَقَالَ «اَلْخُمُسُ» وَ عَنِ اَلْمَعَادِنِ كَمْ فِيهَا فَقَالَ «اَلْخُمُسُ» وَ عَنِ اَلرَّصَاصِ وَ اَلصُّفْرِ وَ اَلْحَدِيدِ وَ مَا كَانَ مِنَ اَلْمَعَادِنِ كَمْ فِيهَا فَقَالَ «يُؤْخَذُ مِنْهَا كَمَا يُؤْخَذُ مِنْ مَعَادِنِ اَلذَّهَبِ وَ اَلْفِضَّةِ ».
