وَ عَنْهُ عَنْ مُحَمَّدِ بْنِ اَلْحُسَيْنِ بْنِ أَبِي اَلْخَطَّابِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ مُحَمَّدِ بْنِ عَلِيِّ بْنِ أَبِي عَبْدِ اَللَّهِ عَنْ أَبِي اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَمَّا يُخْرَجُ مِنَ اَلْبَحْرِ مِنَ اَللُّؤْلُؤِ وَاَلْيَاقُوتِ وَاَلزَّبَرْجَدِ وَ عَنْ مَعَادِنِ اَلذَّهَبِ وَ اَلْفِضَّةِ هَلْ عَلَيْهِ زَكَاتُهَا فَقَالَ» إِذَا بَلَغَ قِيمَتُهُ دِينَاراً فَفِيهِ اَلْخُمُسُ«.
And from him, from Muhammad ibn al-Husayn ibn Abi al-Khattab, from Ahmad ibn Muhammad ibn Abi Nasr, from Muhammad ibn Ali ibn Abi Abdullah, from Abu al-Hasan عليه السلام, peace be upon him, who said:
I (narrator) asked Imam عليه السلام about ‘what is brought out from the sea, of pearls, rubies, and emeralds, and about mines of gold and silver. Is their zakat upon them?’ Imam عليه السلام said: "When its value reaches a dinar, then in it is the fifth (khums)."
