A father taking money from his workplace without his employer's permission

Question:
He says: Honorable Shaykh, may Allah grant you success. My father works for one of the merchants in his store, and my father takes a sum of money from the store every day to meet our needs. I have informed my father that he must seek permission from the store owner so that he does not fall into any doubt. I also tell you, Honorable Shaykh, that my father returns the money immediately as soon as he receives his salary from it, but he did not heed my advice. I fear that this may be forbidden for us. So what is your guidance for him if my father does not stop this action?

Answer:
What is it that you fear? This certainty that it is forbidden. This is forbidden. It is not permissible for him to take from another person's money except with his permission. He must seek permission. Even if he is going to return it, it is not permissible for him to take anything from it, even if he is going to return it, except with the owner's permission. So you must inform him of this, that it is forbidden for him, and it is not permissible except that he says to the store owner, "Lend me." May Allah reward you with good. Lend me until the salary comes, and I will give it to you when the salary arrives. If he lends to him, there is no harm. Yes.
