٧ـ أَحْمَدُ بْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ يُونُسَ بْنِ يَعْقُوبَ قَالَ أَرْسَلْتُ إِلَى أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) أَنَّ لِي إِخْوَةً صِغَاراً فَمَتَى تَجِبُ عَلَى أَمْوَالِهِمُ الزَّكَاةُ قَالَ إِذَا وَجَبَتْ عَلَيْهِمُ الصَّلاَةُ وَجَبَتِ الزَّكَاةُ قُلْتُ فَمَا لَمْ تَجِبْ عَلَيْهِمُ الصَّلاَةُ قَالَ إِذَا اتُّجِرَ بِهِ فَزَكِّهِ.
7. Ahmad ibn Idris has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from Yunus ibn Ya‘qub who has said the following: “I once sent (a letter) to abu ‘Abd Allah, ‘Alayhi al-Salam, to find out when Zakat becomes obligatory for the assets of my small brothers. He (the Imam) said, ‘When Salah (prayer) becomes obligatory up on them, Zakat also become obligatory; however, in the case of those of them on whom Salah (prayer) is not obligatory but their asset is used in business, you must pay Zakat for such assets.’”
