879. hadíth
وَ رُوِيَ عَنِ اَلْعَلاَءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا عَلَيْهِمَا اَلسَّلاَمُ قَالَ: "اَلْمُدَبَّرُ مِنَ اَلثُّلُثِ وَ لِلرَّجُلِ أَنْ يَرْجِعَ فِي ثُلُثِهِ إِنْ كَانَ أَوْصَى فِي صِحَّةٍ أَوْ مَرَضٍ".
It is narrated from al-Ala', from Muhammad ibn Muslim, from one of the Imams (a.s), peace be upon them, who said: "A mudabbar (a slave promised freedom after the owner's death) is considered to be from the one-third (of the estate). A man has the right to retract from his bequest regarding this one-third, whether he made the will during his health or illness."
