What are the legitimate Islamic controls for determining the fee due to a computer maintenance technician whose work relies on using programs that may be pirated, and who provides technical expertise in repairing tangible and intangible defects?

The permissible wage is what the two parties agree upon, for there is no religiously prescribed maximum or minimum for it, even if the effort is slight, provided that the contract does not involve deception or fraud. For leasing and transactions are based on mutual consent. The Fiqh Council has stipulated that there is no specific percentage for profit, while observing Islamic ethics and ensuring the integrity of the transaction, free from fraud, deception, and monopolization. It must be noted that it is not permissible to use pirated software, in consideration of the rights of its owners and because it involves harming others and unlawfully encroaching upon people's property.
