What is the justification for allowing a share of profit when laboring with a managed asset versus sharing offspring from livestock?

Primary text

The permissibility of taking a share of profit when laboring with a managed asset (like a conveyance or *dabba*) is analogous to *Mudarabah* (profit-sharing partnership), because that asset is a tangible item that grows through labor, thus allowing the stipulation of a portion of the growth. Similarly, *Musaqah* (sharecropping/irrigation contract) is likened to *Mudarabah*. However, this analogy does not apply to sharing livestock offspring because the realization of the increase in livestock is not exclusively contingent upon the worker's labor regarding that specific asset, preventing it from being equated to the legitimate profit-sharing partnerships.
