The ruling of Abu Hanifa concerning a contract with differentiated compensation based on time.
General Chapter
Al-Mughni
Book of Leasing
Primary text
Abu Hanifa states that if the worker stitches the garment today, they receive one dirham. If they stitch it tomorrow, the wage shall not exceed one dirham nor fall below half a dirham. This is because the worker was guaranteed half a dirham, which cannot be reduced, and they agreed to one dirham for the greater undertaking, which cannot be exceeded.

This position is invalid because if the contract is sound, the stipulated amount (*al-musamma*) applies. If the contract is void, its existence is equivalent to non-existence, and the customary wage (*ajr al-mithl*) becomes obligatory, as in all void contracts.
