Sunan Abi Da'ud · Hadith 3941
The Book of Manumission of Slaves - كتاب العتق
حدثنا مؤمل، حدثنا إسماعيل، عن أيوب، عن نافع، عن ابن عمر، عن النبي صلى الله عليه وسلم بمعناه قال وكان نافع ربما قال " فقد عتق منه ما عتق " . وربما لم يقله .
The tradition mentioned above has also been transmitted by Ibn 'Umar to the same effect through a different chain of narrators. Nafi' sometimes said: He will be emancipated to the extent of the share which he emancipated, and sometimes he did not say these words.
