If anyone emancipates his share in a slave, he emancipates him (completely) by his property if he has property. The narrator Ibn al-Muthanna did not mention al-Nadr b. Anas. This is the version of Ibn Suwaid.
أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ أَعْتَقَ نَصِيبًا لَهُ فِي مَمْلُوكٍ عَتَقَ مِنْ مَالِهِ إِنْ كَانَ لَهُ مَالٌ وَلَمْ يَذْكُرِ ابْنُ الْمُثَنَّى النَّضْرَ بْنَ أَنَسٍ وَهَذَا لَفْظُ ابْنِ سُوَيْدٍ
[Machine] The Prophet of Allah ﷺ said, "Whoever emancipates a portion from his slave's share, his slave will be freed from his own wealth if he possesses any."
أَنَّ نَبِيَّ اللهِ ﷺ قَالَ مَنْ أَعْتَقَ نَصِيبًا لَهُ مِنْ مَمْلُوكٍ عُتِقَ مِنْ مَالِهِ إِنْ كَانَ لَهُ مَالٌ
[Machine] The Prophet ﷺ said, "Whoever sets free a share for himself from a slave, should set him free from his own wealth if he has it."
أَنَّ النَّبِيَّ ﷺ قَالَ «مَنْ أَعْتَقَ نَصِيبًا لَهُ مِنْ مَمْلُوكٍ عَتَقَ مِنْ مَالِهِ إِنْ كَانَ لَهُ مَالٌ»
[Machine] The Messenger of Allah ﷺ said: "Whoever frees a share for himself from a slave, let him free from his wealth if he has any. If it is not mentioned in his chain of narrators, some of them reported it from Hisham from Nadir ibn Anas, and some of them mentioned it."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ أَعْتَقَ نَصِيبًا لَهُ فِي مَمْلُوكٍ عَتَقَ مِنْ مَالِهِ إِنْ كَانَ لَهُ مَالٌ لَمْ يَذْكُرْ فِي إِسْنَادِهِ بَعْضَ الرُّوَاةِ عَنْ هِشَامٍ عَنِ النَّضْرِ بْنِ أَنَسٍ وَذَكَرَهُ بَعْضُهُمْ
