Are the funds that the husband obtained as a result of exploiting a flaw in the telecommunications company's system permissible for him, under the claim that the company deducts amounts of money from his salary without a just cause?

What a company deducts from an employee's salary falls into two categories:

1. Permissible Deduction: If the deduction is agreed upon in the contract (such as deductions for tardiness or absence), the employee is not permitted to object or attempt to recover the money without the company's knowledge.

2. Forbidden Deduction: If the deduction is not agreed upon, or contradicts what was agreed upon (such as deducting vacation pay, transportation allowance, or agreed-upon overtime), then it is consuming the employee's money unlawfully. In this case, if the employee cannot recover their right through legal means, it is permissible for them to take their money without the company's knowledge, which is known as "the issue of seizing one's right," provided that: They do not take more than their due. They are secure from scandal and punishment. They cannot obtain their right through judicial means. Important Note: One must be careful not to exceed their right or take money to which they are not certain they have a right, as the basic principle is the prohibition of taking others' property.
