If anyone emancipates a share in his slave, he should completely emancipate him if he has money; but if he has none, then slave will be required to work (to pay for his freedom), but he must not be overburdened.
Sunan Abi Dawud Book 31, Hadith 12
← Previous Hadith 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.

Sunan Abi Dawud Book 31, Hadith 11 Next Hadith → If anyone emancipates his share in a slave, he is to be completely emancipated by his money if he has money. But if he has no money, a fair price for the slave should be fixed, and the slave is required to work for his master according to the proportion of his price, but he must not be overburdened.

Abu Dawud said: In the version of both the narrators the words are "he will be required to work and must not be overburdened". This is the version of 'Ali.
