What is the ruling of Islamic law concerning dealing with a person whom you lent a sum of money to help him, then he borrowed another sum from you, then the spouses differed because of that, so are you the oppressor or the oppressed, and who is obliged to repay the debt?

"Ihsan (benevolence) and ithar (altruism) are noble virtues encouraged by Islam. Helping the needy and relieving their distress are among the greatest acts of righteousness by which a servant draws near to their Lord. This is evidenced by the Almighty's saying: 'and prefer [them] over themselves, even though they are in [severe] poverty,' and the Prophet's (peace be upon him) saying: 'Whoever relieves a Muslim of a distress from the distresses of this world, Allah will relieve him of a distress from the distresses of the Day of Resurrection,' and 'The most beloved people to Allah are those who are most beneficial to people. The most beloved deeds to Allah, the Exalted, are joy that you bring to a Muslim, or relieving him of a distress, or paying off his debt, or warding off his hunger.'

There is no blame upon you for concealing the car's secret, because a secret is a trust, and divulging it is a betrayal. You have the right to demand that the debtor pay off their debt, and the money you took from them is not obligatory for you to return, as it serves as a repayment for part of their debt to you. The woman's accusation that you caused the disruption of her relationship with her husband is of no consideration. You should treat her husband as a stranger if he is indeed a stranger to you."
