Costs of Treatment Should Be Deducted From Your Salary
Question :
Outside of work time, I got an accident. I needed. treatment, and since I could not afford the cost of that treatment, I claimed that the accident was job-related. The company I work for paid for the treatment, though I now regret what I did. Is what I did unlawful?
Answer:
You are required to inform your company about what you did and you should offer either to return the money they paid for the treatment or to have that money deducted from your salary. If they forgive you that money, there is no longer any burden upon you. If not, you must return to them that money. And ask Allâh Almighty to forgive you for your deception and wrongdoing.
