Is it permissible for horse racers to provide the stake themselves?

The questioner : The ready-made gambling, for example, where the racers compete on a horse or on something else, is permissible, meaning the stake must come from another person, right?

The Shaykh : If it comes from another person, it is not a stake, my sir; it is a prize. For example, if a third person says, "Whoever wins the race among you gets so much and so much," that is a prize.

The questioner : Does he not work with this? No, no.

The Shaykh : It is from both parties, meaning each one puts in one hundred, and says, "Whoever wins among us takes the two hundred."

The questioner : Very well.

The Shaykh : No, if it is from another person, and you give it to them now? What would it be? It would be a prize. I saw two people racing, and I said, "Go ahead, whoever wins among you, I will give him one hundred riyals." That is a prize from me; it does not enter into the stake of this gambling.

The questioner : But if it is from them, here.

The Shaykh : This is what the Lawgiver excluded, if it is from them.
