Thank you for your question and for asking about your religion.
Indeed your already know what you are doing is wrong.
Wabisah bin Ma'bad (ra) said
"I came to the Messenger of Allah (sas) and he said: "You have come to ask about righteousness ?" " Yes," I answered. He said: "Consult your heart. Righteousness is that about which the soul feels tranquil and the heart feels tranquil, and sin is what creates restlessness in the soul and moves to and fro in the breast, even though people give you their opinion (in your favour) and continue to do so."
A good hadith transmitted from the Musnads of the two Imams, Ahmad bin Hanbal and Al-Darimi
The question is What should you do about it?
I recommend first to give up this sin and not ever return to it and repent to Allah the Most Forgiving. I do t know what you must also do in addition. Do you need to admit to your father and seek his forgiveness Or repay him all the money you took without confessing. Perhaps you can do either. Do you know the answer @muftisaab?
