605. hadíth
وَ رَوَى مُحَمَّدُ بْنُ عِيسَى اَلْعُبَيْدِيُّ قَالَ كَتَبَ أَحْمَدُ بْنُ حَمْزَةَ إِلَى أَبِي اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ: مُدَبَّرٌ وُقِفَ ثُمَّ مَاتَ صَاحِبُهُ وَ عَلَيْهِ دَيْنٌ لاَ يَفِي بِمَالِهِ فَكَتَبَ عَلَيْهِ اَلسَّلاَمُ "يُبَاعُ وَقْفُهُ فِي اَلدَّيْنِ".
Muhammad ibn Isa Al-Ubaydi narrated that Ahmad ibn Hamzah wrote to Abu Al-Hasan, peace be upon him, regarding a mudabbar (a slave who was set to be freed upon his owner's death) who was placed in an endowment (waqf), and then his owner died while owing a debt that could not be covered by his remaining wealth. Imam (a.s) wrote in response: "The endowment is to be sold to settle the debt."
