Is it permissible to take from the procrastinating debtor's money, which is known as "al-Zafar" (taking by force what one is owed), if he had promised a salary increase and to cover car maintenance, then reneged on his promise and refused to communicate?

Increases promised to an employee but not stipulated in the contract are considered a promise. The general rule is that fulfilling a promise is recommended but not obligatory, unless the person to whom the promise was made undertook something due to the promise and would suffer harm if it were rescinded; in such a case, fulfilling it becomes obligatory. If the promise of an increase is not linked to additional work or extra effort, the institution is not obliged to fulfill it. However, if the promise is linked to an increase in the employee's work and additional burden, the institution must fulfill it, and the employee has a right to it.

The issue of "al-Zafar" (taking one's right by force or stealth) applies to someone whose right has been unjustly withheld and who cannot obtain it except by such means. It is not permissible for the employee to take the promised increases through trickery or embezzlement unless it is proven that they are his right and the company prevented him from receiving them, and he had no other way to obtain them except through trickery. If the promise of a salary increase and car repair was not linked to additional work, the employee is not entitled to anything, and it is not permissible for him to take money from his employer.
