Sunan Abi Da'ud · Hadith 3943
The Book of Manumission of Slaves - كتاب العتق
حدثنا إبراهيم بن موسى الرازي، أخبرنا عيسى بن يونس، حدثنا عبيد الله، عن نافع، عن ابن عمر، قال قال رسول الله صلى الله عليه وسلم " من أعتق شركا من مملوك له فعليه عتقه كله إن كان له ما يبلغ ثمنه وإن لم يكن له مال عتق نصيبه " .
Ibn 'Umar reported the Messenger of Allah (ﷺ) as saying: If anyone emancipates his share in a slave, he should emancipate him completely if he has enough money to pay the full price ; but if he has none, he will be emancipated to the extent of his share.
