Is a condition specifying the lineage/loyalty (*wala'*) of an emancipated slave valid?

Primary text

Any condition stipulating that the lineage or loyalty (*wala'*) of an emancipated slave belongs to someone other than the one who actually frees the slave is void. There is no known disagreement on the nullity of such a condition. Evidence for this is the narration of Aisha concerning Barirah, where the Prophet, peace be upon him, commanded her purchase and emancipation, stating, "The *wala'* belongs only to the one who frees [the slave]." In another narration, the Prophet declared generally, "Whoever stipulates a condition not in the Book of Allah, it is void, even if it were one hundred conditions; the judgment of Allah is more deserving, and the condition of Allah is more binding." Additionally, the *wala'* cannot be transferred, as the Prophet forbade its sale or gift, affirming that it belongs only to the emancipator. The *wala'* is analogous to kinship, which cannot be stipulated for another, and it is a legal consequence of emancipation, similar to how the legal consequence of marriage cannot be stipulated for someone who is not marrying.
