A craftsperson is promised payment when the job is completed. Once satisfactory work is finished and funds are available, delaying the agreed payment without cause violates fairness. For weekly or monthly contracts, timely payment under the agreed schedule serves the same principle.
A worker’s time, labor, and livelihood deserve respect. Clear terms and documented payments can prevent disputes. If a genuine difficulty arises, communicate honestly and promptly rather than making repeated excuses.
The ending هُ in both أَجْرَهُ and عَرَقُهُ refers to the الْأَجِيرَ, the worker.
