عَلِيُّ بْنُ مَهْزِيَارَ عَنْ فَضَالَةَ وَاِبْنِ أَبِي عُمَيْرٍ عَنْ جَمِيلٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنْ مَعَادِنِ اَلذَّهَبِ وَ اَلْفِضَّةِ وَاَلصُّفْرِ وَاَلْحَدِيدِ وَ اَلرَّصَاصِ فَقَالَ» عَلَيْهَا اَلْخُمُسُ جَمِيعاً«.
Ali ibn Mahziyar, from Fadalah and Ibn Abi Umayr, from Jamil, from Muhammad ibn Muslim, from Abu Ja’far عليه السلام, peace be upon him, who said:
I (narrator) asked Imam عليه السلام about ‘mines of gold, silver, brass (sufr), iron, and lead.’ Imam عليه السلام said: "Upon all of them is the fifth (khums)."
