Is it permissible for an employee to take a portion of his work's profits without the employer's knowledge if the latter does not acknowledge his right after an absence due to illness?

It is not permissible for a worker to take from the employer's money what he claims is his right without the employer's knowledge, because money is a trust, and the trustee must return the trust to its owner. Allah Almighty has commanded the fulfillment of trusts, and the Prophet, peace and blessings be upon him, forbade treachery, even against one who has betrayed. The Permanent Committee has issued a fatwa stating that it is not permissible for a worker to take his salary from the grocery store's money without the owner's knowledge and permission. Rather, he should demand his salary from the employer or file a complaint with the competent authorities.

Shaykh al-Islam Ibn Taymiyyah differentiated between two types: 1. If the reason for entitlement is apparent, such as a wife's maintenance, then it is permissible to take without permission. 2. If the reason for entitlement is not apparent, such as the denial of a debt or usurpation without clear evidence, there are two opinions. However, the more correct opinion is that it is not permissible to take, based on the hadith: "Return the trust to the one who entrusted you, and do not betray the one who betrayed you." This is because taking money without permission and without an apparent entitlement is considered treachery, and treachery is forbidden, and it is not permissible to recover a right through it.
