Hadith 7113- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ جَمِيعاً عَنِ ابْنِ مَحْبُوبٍ عَنْ أَبِي أَيُّوبَ عَنْ سَمَاعَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنْ رَجُلٍ أَوْصَى أَنْ يُعْتَقَ عَنْهُ نَسَمَةٌ بِخَمْسِمِائَةِ دِرْهَمٍ مِنْ ثُلُثِهِ فَاشْتُرِيَ نَسَمَةٌ بِأَقَلَّ مِنْ خَمْسِمِائَةِ دِرْهَمٍ وَفَضَلَتْ فَضْلَةٌ فَمَا تَرَى قَالَ تُدْفَعُ الْفَضْلَةُ إِلَى النَّسَمَةِ مِنْ قَبْلِ أَنْ تُعْتَقَ ثُمَّ تُعْتَقُ عَنِ الْمَيِّتِ.
13. A number of our people have narrated from Sahl ibn Ziyad and Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad all from ibn Mahbub from abu Ayyub from Sama‘ah who has narrated the following: “I once asked abu ‘ Abd Allah (a.s.), about the case of a man who made a will to set free a slave for five hundred dirham from the one-third of his legacy. A slave was bought for less than five hundred dirham and something remained extra. What do you say about it? He (the Imam) said, ‘Give the extra to the slave before setting him free, then set him free for the deceased.’”
