وَلَا يُعْطِي أُجْرَةَ الْجَزَّارِ مِنْهَا.
Translation: The butcher’s wages are not to be paid from the sacrificial animal.
Ujrah is a contractual wage.
Example: the agreed slaughter fee should be paid from separate funds, not deducted from the offering’s meat or skin.
A genuine charitable gift and payment for labor are not the same transaction.
