Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 1|Chapter 47
وَ رُوِيَ عَنِ اَلْعَلاَءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا عَلَيْهِمَا اَلسَّلاَمُ: فِي اَلرَّجُلِ يُعْتِقُ غُلاَمَهُ أَوْ جَارِيَتَهُ عَنْ دُبُرٍ مِنْهُ ثُمَّ يَحْتَاجُ إِلَى ثَمَنِهِ أَ يَبِيعُهُ قَالَ "لاَ إِلاَّ أَنْ يَشْتَرِطَ عَلَى اَلَّذِي يَبِيعُهُ إِيَّاهُ أَنْ يُعْتِقَهُ عِنْدَ مَوْتِهِ".
It is narrated by al-Ala', from Muhammad ibn Muslim, from one of the Imams عليه السلام, peace be upon them, regarding a man who frees his male or female slave as a mudabbar (to be freed after his death) and then becomes in need of the slave's price. Imam عليه السلام said: "No, he may not sell the slave-unless he stipulates to the buyer that the slave must be freed at the time of his death."
