ANSWER:

If it was a gift for a person in exchange of something he had done or tried to do, this is permissible as in the case I challenge someone that if he climbed that mountain, I will give him money for that but I am challenging him as I don’t believe that he can! 

But if this money was for no work as if I say that this team will win and he says that the other team will win, and i say if your team wins, i will give you this or that, this is not permissible as he didn’t work for it and it is extravagance from my part. 

Is betting haram? What if from both sides (not one side bet)
