A man declared that his slave would be free after his death, but he had no other property. So the Prophet ﷺ ordered (to sell him). He was then sold for seven hundred or nine hundred (dirhams). (Using translation from Abū Dāʾūd 3955)   

البيهقي:٢١٥٤٦ – أَخْبَرَنَا عَلِيُّ بْنُ أَحْمَدَ بْنِ عَبْدَانَ أنبأ أَحْمَدُ بْنُ عُبَيْدٍ الصَّفَّارُ ثنا إِسْمَاعِيلُ بْنُ إِسْحَاقَ ثنا مُسَدَّدٌ ثنا هُشَيْمٌ عَنْ عَبْدِ الْمَلِكِ بْنِ أَبِي سُلَيْمَانَ عَنْ عَطَاءٍ وَإِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ عَنْ سَلَمَةَ بْنِ كُهَيْلٍ عَنْ عَطَاءٍ عَنْ جَابِرِ بْنِ عَبْدِ اللهِ أَنَّ رَجُلًا أَعْتَقَ غُلَامًا

عَنْ دُبُرٍ مِنْهُ وَلَمْ يَكُنْ لَهُ مَالٌ غَيْرُهُ فَأَمَرَ رَسُولُ اللهِ ﷺ فَبِيعَ بِتِسْعِمِائَةِ دِرْهَمٍ أَوْ بِسَبْعِمِائَةِ دِرْهَمٍ هَذَا هُوَ الصَّحِيحُ
