What should a husband do who divorced his wife and has some of her belongings which he has not returned to her, and he offered her a sum of money as compensation, but she refused, saying: "I want them on the Day of Resurrection," in order to clear his conscience?

You must absolve yourself of injustices today before the Day of Judgment, and he who repents of a sin is like one who has no sin. If you offered your ex-wife the value of what you took from her, and even increased the amount, but she refused, then you have done what was required of you. Try to deliver the money to her by every possible means. If that is impossible and you are certain it cannot be delivered, then donate it on her behalf, and she will receive the reward for the charity.
