 ٧ـ أَحْمَدُ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنِ الرِّضَا (عَلَيْهِ السَّلام) قَالَ سُئِلَ عَنْ قَوْلِ الله عَزَّ وَجَلَّ وَاعْلَمُوا أَنَّما غَنِمْتُمْ مِنْ شَيْ‏ءٍ فَأَنَّ لله خُمُسَهُ وَلِلرَّسُولِ وَلِذِي الْقُرْبى‏ فَقِيلَ لَهُ فَمَا كَانَ لله فَلِمَنْ هُوَ فَقَالَ لِرَسُولِ الله (صَلَّى اللهُ عَلَيْهِ وَآلِه) وَمَا كَانَ لِرَسُولِ الله فَهُوَ لِلامَامِ فَقِيلَ لَهُ أَ فَرَأَيْتَ إِنْ كَانَ صِنْفٌ مِنَ الاصْنَافِ أَكْثَرَ وَصِنْفٌ أَقَلَّ مَا يُصْنَعُ بِهِ قَالَ ذَاكَ إِلَى الامَامِ أَ رَأَيْتَ رَسُولَ الله (صَلَّى اللهُ عَلَيْهِ وَآلِه) كَيْفَ يَصْنَعُ أَ لَيْسَ إِنَّمَا كَانَ يُعْطِي عَلَى مَا يَرَى كَذَلِكَ الامَامُ.
 7. Ahmad has narrated from Ahmad ibn Muhammad ibn abu Nasr who has said the following. “Once a person asked al-Rida  about the words of Allah, the Most Majestic, the Most gracious, “Know that whatever property you may gain, one fifth belongs to God, the Messenger, the kindred,. .” (8:41) It then was asked, “The portion that belongs to Allah to who does it go?” The Imam  said, “It belongs to the Messenger of Allah and whatever belongs to the Messenger of Allah it belongs to the Imam.” Another question said, “If one of the categories of welfare recipient would more and the other category less then how it is dealt with?” The Imam  said, “It is left to the discretion of the Imam consider how the Messenger of Allah dealt with such cases. Is it not the case that he used his own discretion and distribute as he would consider proper? The Imam would deal with such case in the same way.”
