حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ مَنْ أَعْتَقَ شِرْكًا لَهُ فِي مَمْلُوكٍ أُقِيمَ عَلَيْهِ قِيمَةَ الْعَدْلِ فَأَعْطَى شُرَكَاءَهُ حِصَصَهُمْ وَأُعْتِقَ عَلَيْهِ الْعَبْدُ وَإِلاَّ فَقَدْ عَتَقَ مِنْهُ مَا عَتَقَ ‏"‏ ‏.‏ ‏.‏

Narrated ath-Thalabb

On the authority of his father: A man emancipated his share in a slave. The Prophet (ﷺ) did not put the responsibility on him to emancipate the rest.

Ahmad said: The name Ibn al-Thalabb is to be pronounced with a ta' (and not with tha). As Shu'bah could not pronounce ta, he said tha.
