4ـ مُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ عِيصِ بْنِ الْقَاسِمِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) فِي الزَّكَاةِ فَقَالَ مَا أَخَذَ مِنْكُمْ بَنُو أُمَيَّةَ فَاحْتَسِبُوا بِهِ وَلاَ تُعْطُوهُمْ شَيْئاً مَا اسْتَطَعْتُمْ فَإِنَّ الْمَالَ لاَ يَبْقَى عَلَى هَذَا أَنْ تُزَكِّيَهُ مَرَّتَيْنِ.
4. Muhammad ibn ’Isma’il has narrated from al-Fadl ibn Shadhan from Safwan ibn Yahya from ‘Is ibn al-Qasim who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘Whatever banu ‘Umayyah make you to pay, count it (as Zakat) and do not give anything to them if you can; no assets will be left if you pay twice.’”
