Jabir bin'Abdullah (RA) reported that sAllah's Apostle (ﷺ) made it obligatory for every tribe (the payment) of blood-wit; he then also made it explicit that it is not permissible for a Muslim to make himself the ally (of the slave emancipated by another) Muslim without his permission. He (the narrator further added): I was informed that he (the Holy Prophet) cursed the one who did that (and it was recorded) in his Sahifa (in a document).

Hadith Commentary: Benefits and Issues: If by "tawali" is meant merely the relationship of cooperation and mutual support, then this is permissible with the permission of the master who has granted freedom. However, if what is meant is an attribution (of lineage), then this is not permissible, because the Prophet (sallallahu alayhi wa sallam) forbade the selling or gifting of wala’ (the bond of allegiance) of a freed person. Therefore, when the implied meaning (mafhum mukhalif) is contrary to the explicit meaning (mantuq), it is not considered as proof or evidence.
Thus, to establish from this hadith that the implied meaning (mafhum mukhalif) or dalil al-khitab is not a valid proof is incorrect. Except for Imam Abu Hanifah rahimahullah, the majority of jurists (with six conditions) consider all types of implied meaning (mafhum mukhalif), except for that of a proper noun (laqab), to be valid. And the purpose of making blood money (diyah) obligatory upon every family is that, in cases of accidental killing (qatl khata’) and quasi-intentional killing (shibh al-amd), the members of the killer’s family will pay the blood money (diyah).
