Winning money for catching the ball in the SA20 tournament
Q: There is a cricket tournament called the SA20. In the SA20 tournament, if the batsman hits a 6, and someone from the crowd catches the ball with 1 hand, they win a share of 2 million rands. You do not have to enter any competition or anything, you just have to catch the ball with 1 hand and you win a share of 2 million rands with other individuals who caught the ball with one hand.
Now I caught the ball with one hand and I'm entitled to the share. Now the sponsor of this competition is Betway. Is the money haraam even though I just won a competition without any money added to it and without taking pictures of the check with the name Betway. I just won a competition. Is the money haraam if it comes from that company?
