Is paying only 50 Riyals to a maid who worked for one day, knowing that the agreed-upon wage for every Friday is 50 Riyals and that the maid asked for 100 Riyals, considered an injustice to her?

The tenant must pay the workers their due wages, for the Prophet, peace and blessings be upon him, said: "Give the hired worker his wages before his sweat dries." If the worker is absent, his right is considered a trust, for Allah, the Almighty, says: "Indeed, Allah commands you to render trusts to whom they are due." Therefore, if you trust the woman to deliver the amount to its owner, then give her the wages due for one day. If you do not trust her, then keep the money until its owner comes.
