Is it permissible for a person to kill one who has wronged him in his wealth, based on the hadith of the Prophet (peace and blessings be upon him), “Whoever is killed defending his wealth is a martyr”?

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: I entrusted a man with money, and every time I demanded it from him, he denied it to me and did not give it to me. He says: I have decided to kill him, O Honorable Shaykh, because the Messenger (peace and blessings be upon him) said, “Whoever is killed defending his wealth is a martyr.” So did the Shaykh do it?

Answer:
The one who gave it to you did not rob you; it was you who gave it to him. “Whoever is killed defending his wealth” applies if someone comes to forcibly seize your wealth. As for this case, it was you who lent it to him, and you who empowered him over it. You are the one who was negligent in demanding it from him if it happened, otherwise Allah will compensate you. You are the one who was negligent in this. He says: Honorable Shaykh. Do you have evidence against him to bring his case to the court? Yes.
