A man works in an amusement park in one of the gambling games; what is the ruling on the salary he receives in exchange for this work?

The questioner : Yesterday, O Shaykh, I was speaking with a man, advising him regarding the issue of singing. He told me, "All my money is haram." I asked him, "What do you do?" He said, "I am an employee in one of these amusement parks or game centers, working at one of the kiosks." He told me, "I take a salary; I receive a salary from this work, and this entire salary is haram." What is your opinion, O Shaykh? Is his statement correct?
The student : What does he sell?

The questioner : Games, yes.
The student : He throws the wheel, right? He takes them.
Another student: These are gambling games, right?
The student : Because you place a bottle, for example, and throw a ring; with whichever ring it lands, you take them. You pay ten qirsh, for example, which might be the equivalent.

The Shaykh : Gambling, gambling, gambling.

The questioner : So, is this the money he takes as a salary from this institution where he works?

The Shaykh: Of course.

The questioner : It is haram.
The student : For free, O Shaykh? I have never won, praise be to Allah.
Another student: O our Shaykh, he is sitting in the middle of the circle; what is your opinion?
