أَبَا عَبْدِ اللَّهِ ع عَنْ رَجُلٍ أَقَرَّ لِوَارِثٍ لَهُ وَ هُوَ مَرِيضٌ بِدَيْنٍ عَلَيْهِ فَقَالَ يَجُوزُ إِذَا كَانَ الَّذِي أَقَرَّ بِهِ دُونَ الثُّلُثِ[1].
I asked Abu Abdullah (as), about a man who, while ill and in debt, acknowledged a right for one of his heirs. Imam (as) said: "It is permissible if what he acknowledged is less than one-third (of his wealth)."
