How can a sum of 25,000 EGP, which has become 44,000 EGP with interest, lent by a wife to her husband since 1993, be recovered, given that he denies receiving it, and that the amount was secured by a deposit and the bank is demanding the wife repay the sum?

The husband must return the amount he borrowed from his wife; otherwise, he is consuming what is unlawful. This is supported by several prophetic hadiths warning against taking people's money with the intention of not returning it, including the hadith: "Whoever takes people's money intending to repay it, Allah will repay it on his behalf, and whoever takes it intending to destroy it, Allah will destroy him."

And the hadith: "There is no Muslim who incurs a debt, and Allah knows that he intends to repay it, except that Allah will repay it on his behalf in this world."

And the hadith: "Any man who borrows a debt from another man, and Allah knows that he does not intend to repay it to him, so he deceives him by Allah and unlawfully takes his money, will meet Allah, the Mighty and Majestic, on the Day he meets Him as a thief."

If the husband does not return the money, the wife has the right to file a lawsuit. The wife must also repent to Allah for dealing with interest-based banks.
