The Ruling on Disposing of Another Person's Property Without His Permission

Question:
What is your opinion of a man who has a car that does not belong to him, but rather to his brother, for example, and he says to another man, "If you lend me one thousand riyals for two months, I will give it to you"? What is your opinion of a man who has a car that does not belong to him, but rather to his brother, for example, and he says to another man, "If you lend me one thousand riyals for two months, I will give it to you"?

Answer:
I mean, he tells his brother that the prayer has been sufficient for him, and he gives it to him as if it were his prayer. I mean, he deceives people, taking people's money and giving it to people because they gave him money. He takes people's money, whether it is his brother's or someone else's. This is a matter, and I seek refuge in Allah, of a specific and wicked person, and generally, it is not permissible to obey him. It is not permissible to obey him with money until he deceives people with their money or their cars. This is a great evil. He should not deceive anyone. It is not permissible for a Muslim to encroach upon his brother's money, even if his money was given to him, even if his money was claimed for him, even if he was afraid for him. He must not encroach upon people, and he should not take his brother's money, nor his father's money, nor his mother's money, nor anything else. He must be cautious of that, and be trustworthy, not a traitor, and not encroach upon anyone's wealth.
