The ruling on one who took money from his brother without his knowledge and then repented

Question:
From a listener. He says in his message: About five years ago, when I was sixteen years old, I took a sum of money from my brother, approximately two thousand and one hundred riyals, without his knowledge. I have now repented to Allah the Exalted and committed myself to obedience. What is obligatory for me now, Your Eminence the Shaykh? Knowing that I have debts, and my brother is a man of wealth and is rich.

Answer:
You must inform him and ask for his forgiveness. If he forgives you, praise be to Allah; otherwise, you must pay him back if you are able. Allah the Exalted said: and He the Exalted said: So you must repent to Allah, feel remorse, and resolve to pay him his due and return the money to him, unless he forgives you and waives it, in which case may Allah reward him with good. The expectation is that he will forgive you, as long as he is well, praise be to Allah. The expectation is that he will forgive him. So ask him for forgiveness, repent to Allah for your action, and proceed with good. If he refuses, you must fulfill the obligation once you are able.
