What is the ruling on a nominal purchase of a property from a broker without payment or documentation, then selling it to another buyer to take the price difference and pay the agreed-upon amount to the seller?

This transaction can be understood in two ways:

1. The questioner may have purchased the property but not yet paid the price or formally documented the sale. This sale is valid if the broker was authorized by the owner. Delaying the payment or not documenting the sale in writing does not invalidate the sale. The buyer may sell the property after taking possession of it. 2. There might not have been an actual sale, and the property ownership was not transferred to the questioner. Instead, it was merely a promise of a sale. In this case, the second sale is invalid because the questioner would be selling what she does not own, and Islamic law has prohibited this.
