What is the ruling on exchanging old gold for new gold while paying the difference?

The questioner : Blessed fasting, we hope for its blessing. When the news came, we sent it out to the sun, and we were in the garden, we did not separate, we did not eat or drink, and how much of the night we fasted. Is it obligatory for us to make it up, or not?

The Shaykh : This was mentioned in the questions.

The questioner : We are in distress, may you live long.

The Shaykh : Yes, a word. Any word, I start with the questions and start with the students, any of them who writes

The questioner : May Allah reward you with good. Done.

The Shaykh : Now it is the administration's turn.

The questioner : May Allah be pleased with you, the urgent question, the urgent question, the urgent question,

The Shaykh : Okay, okay, is there anyone writing?

The questioner : The questioner says: The Messenger of Allah (peace and blessings be upon him) said, meaning, gold for gold, , that he takes used gold, for example, the price of the gram is thirty riyals, and sells the new gold at a price of forty riyals per gram, so what is the ruling on this?

The Shaykh : The ruling on this is not permissible, meaning it is not permissible to exchange bad gold for good gold and give the difference. This is forbidden and not permissible. What indicates this is what is established in the two Sahihs and others in the story of Bilal (may Allah be pleased with him). He came to the Prophet (peace and blessings be upon him) with good dates and he said to him , but we buy . The Messenger of Allah (peace and blessings be upon him) said, "No, do not do it. It is pure riba, pure riba." So the Messenger (peace and blessings be upon him) made it clear that increasing what requires equality due to a difference in description is pure riba, and that it is not permissible for a person to do it. But the Messenger of Allah (peace and blessings be upon him), as was his custom, guided him to the permissible way and said, . Al-Jam' is the bad dates gathered from various types. .
So the Prophet (peace and blessings be upon him) guided him to sell the bad dates for dirhams and then buy something good with the dirhams. And based on this, we say if a woman has bad gold, or gold, or gold that people have stopped wearing, she sells it in the market, then takes the dirhams and buys good gold with them that she chooses. This is the way our Prophet (peace and blessings be upon him) guided to.
