٢- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ صَفْوَانَ قَالَ سَأَلْتُ الرِّضَا (عَلَيْهِ السَّلام) وَمُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ صَفْوَانَ وَأَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ قَالا سَأَلْنَا أَبَا الْحَسَنِ الرِّضَا (عَلَيْهِ السَّلام) عَنْ رَجُلٍ أَوْصَى بِسَهْمٍ مِنْ مَالِهِ وَلا يُدْرَى السَّهْمُ أَيُّ شَيْ‏ءٍ هُوَ فَقَالَ لَيْسَ عِنْدَكُمْ فِيمَا بَلَغَكُمْ عَنْ جَعْفَرٍ وَلا عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلام) فِيهَا شَيْ‏ءٌ قُلْنَا لَهُ جُعِلْنَا فِدَاكَ مَا سَمِعْنَا أَصْحَابَنَا يَذْكُرُونَ شَيْئاً مِنْ هَذَا عَنْ آبَائِكَ فَقَالَ السَّهْمُ وَاحِدٌ مِنْ ثَمَانِيَةٍ فَقُلْنَا لَهُ جُعِلْنَا فِدَاكَ كَيْفَ صَارَ وَاحِداً مِنْ ثَمَانِيَةٍ فَقَالَ أَمَا تَقْرَأُ كِتَابَ اللهِ عَزَّ وَجَلَّ قُلْتُ جُعِلْتُ فِدَاكَ إِنِّي لأقْرَؤُهُ وَلَكِنْ لا أَدْرِي أَيُّ مَوْضِعٍ هُوَ فَقَالَ قَوْلُ اللهِ عَزَّ وَجَلَّ إِنَّمَا الصَّدَقاتُ لِلْفُقَراءِ وَالْمَساكِينِ وَالْعامِلِينَ عَلَيْها وَالْمُؤَلَّفَةِ قُلُوبُهُمْ وَفِي الرِّقابِ وَالْغارِمِينَ وَفِي سَبِيلِ اللهِ وَابْنِ السَّبِيلِ ثُمَّ عَقَدَ بِيَدِهِ ثَمَانِيَةً قَالَ وَكَذَلِكَ قَسَمَهَا رَسُولُ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) عَلَى ثَمَانِيَةِ أَسْهُمٍ فَالسَّهْمُ وَاحِدٌ مِنْ ثَمَانِيَةٍ. 
2. Ali ibn Ibrahim has narrated from his father from Safwan from abu af-Hassan, al-Rida’ , and Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Safwan and Ahmad ibn Muhammad from ibn abu Nasr who have said the following: “We once asked abu al-Hassan, al-Rida’ , about the case of a man who has made a will about a share of his legacy and it is not known how much a share is. He (the Imam) asked, ‘Have you not received anything about it from Ja‘far, or abu Ja‘far, ‘Alayhim al-Salam?’ We replied, ‘We pray to Allah to keep our souls in service for your cause, we have not heard our people mention anything about it from your ancestors.’ He (the Imam) said, ‘A share is one of eight.’ We said, ‘We pray to Allah to keep our souls in service for your cause, how it has become one of eight?’ He (the Imam) said, ‘Have you not read the book of Allah, most Majestic, most Glorious?’ I said, ‘I pray to Allah to keep my soul in service for your cause, I read but do not know in which passage it is.’ He (the Imam) said, ‘It is in the words of Allah, most Majestic, most Glorious, “Charity is only for the poor, destitute, Zakat collectors, people inclined to the religion, slaves, debtors, in the way of Allah and for those who deplete their supplies on a journey.” (9:60)’ He (the Imam) then formed eight with his hand and said, ‘This is how the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, distributed in eight shares, thus, a share is one out of eight.’”
