On his father's authority (this is AbulWalid's version): A man emancipated a share in a slave and the matter was mentioned to the Prophet ﷺ. He said: Allah has no partner. Ibn Kathir added in his version: The Prophet ﷺ allowed his emancipation.  

أَنَّ رَجُلاً أَعْتَقَ شِقْصًا لَهُ مِنْ غُلاَمٍ فَذَكَرَ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ لَيْسَ لِلَّهِ شَرِيكٌ زَادَ ابْنُ كَثِيرٍ فِي حَدِيثِهِ فَأَجَازَ النَّبِيُّ ﷺ عِتْقَهُ  

A man emancipated his share in a slave. The Prophet ﷺ allowed his (full) emancipation, and required him to pay the rest of his price. (Using translation from Abū Dāʾūd 3934)   

أَنَّ رَجُلًا أَعْتَقَ شِقْصًا مِنْ مَمْلُوكٍ فَأَجَازَ النَّبِيُّ ﷺ عِتْقَهُ وَغَرَّمَهُ بَقِيَّةَ ثَمَنِهِ  

[Machine] "A man from these two (groups) freed his slave, so the Messenger of Allah ﷺ said, 'He is completely free, as there is no partner to Allah.'"  

أَنَّ رَجُلًا مِنْ هُذَيْلٍ أَعْتَقَ شَقِيصًا لَهُ مِنْ مَمْلُوكٍفَقَالَ رَسُولُ اللهِ ﷺ هُوَ حُرٌّ كُلُّهُ لَيْسَ لِلَّهِ شَرِيكٌ  

[Machine] A man freed a slave, so the Prophet ﷺ approved his act of emancipation and said, "Allah has no partner."  

أَنَّ رَجُلًا أَعْتَقَ شِقْصًا مِنْ مَمْلُوكٍ فَأَجَازَ النَّبِيُّ ﷺ عِتْقَهُ وَقَالَ «لَيْسَ لِلَّهِ شَرِيكٌ»
