Hadith 20245ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ إِسْمَاعِيلَ بْنِ مَرَّارٍ عَنْ يُونُسَ عَنِ الْعَلاَءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ أَنَّهُ قَالَ كُلُّ مَالٍ عَمِلْتَ بِهِ فَعَلَيْكَ فِيهِ الزَّكَاةُ إِذَا حَالَ عَلَيْهِ الْحَوْلُ قَالَ يُونُسُ تَفْسِيرُ ذَلِكَ أَنَّهُ كُلُّ مَا عُمِلَ لِلتِّجَارَةِ مِنْ حَيَوَانٍ وَغَيْرِهِ فَعَلَيْهِ فِيهِ الزَّكَاةُ.
5. Ali ibn Ibrahim has narrated from his father from ’Isma‘il ibn Marrar from Yunus from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “He (the Imam) (a.s.), has said, ‘Any asset with which you work is subject to Zakat when one year passes.’ Yunus has said that the explanation for it is that whatever asset is used in business, animals or other assets, it is subject to Zakat.”
