Is the money the questioner takes, which is one or two dinars out of a total of 20 dinars or more, considered income from work, or theft, knowing that she intends to return it, and that her employer does not pay her share of the agreed-upon wage, and the state delays in paying its share?

The questioner's sister is not permitted to take anything from the business's income without the owner's permission. It is not valid to consider this a debt upon her, as a debt requires the creditor's consent and knowledge. Furthermore, a low salary or illness do not justify infringing upon the business owner's money. She must repent and return whatever she took without permission.
