I say, and with God's success: Work is a contract between two parties. If there is an agreement between them on a specific work and a specific fee, then she is entitled to what was agreed upon in terms of money if she performed the work. If there is no verbal or customary agreement regarding the work or the money, then she is not entitled to a fee; because she would be considered a volunteer for what she has done. If her work has a financial return, he should honor her and reciprocate her kindness with kindness. If the work has no financial return, then her reward and his reward are with God Almighty, and God knows best.
