وَ عَنْهُ عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ مُحَمَّدِ بْنِ زِيَادٍ عَنْ عُمَرَ بْنِ أُذَيْنَةَ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ:» فِي اَلذَّهَبِ إِذَا بَلَغَ عِشْرِينَ دِينَاراً فَفِيهِ نِصْفُ دِينَارٍ وَ لَيْسَ فِيمَا دُونَ اَلْعِشْرِينَ شَيْءٌ وَ فِي اَلْفِضَّةِ إِذَا بَلَغَتْ مِائَتَيْ دِرْهَمٍ خَمْسَةُ دَرَاهِمَ وَ لَيْسَ فِيمَا دُونَ اَلْمِائَتَيْنِ شَيْءٌ فَإِذَا زَادَتْ تِسْعَةٌ وَ ثَلاَثُونَ عَلَى اَلْمِائَتَيْنِ فَلَيْسَ فِيهَا شَيْءٌ حَتَّى تَبْلُغَ اَلْأَرْبَعِينَ وَ لَيْسَ فِي شَيْءٍ مِنَ اَلْكُسُورِ شَيْءٌ حَتَّى تَبْلُغَ اَلْأَرْبَعِينَ وَ كَذَلِكَ اَلدَّنَانِيرُ عَلَى هَذَا اَلْحِسَابِ«.
And from him, from Ali ibn Asbat, from Muhammad ibn Ziyad, from Umar ibn Udhaynah, from Zurarah, from Abu Ja’far عليه السلام, peace be upon him, who said:
Imam عليه السلام said: “In gold, when it reaches twenty dinars, there is half a dinar due on it, and there is nothing due on what is less than twenty. And in silver, when it reaches two hundred dirhams, there are five dirhams due, and there is nothing due on what is less than two hundred. Then if thirty-nine are added to the two hundred, there is nothing due on it until it reaches forty. And there is nothing due on any fractions until it reaches forty. And likewise the dinars are according to this calculation.”
