Can he eat from his father’s wealth although its source is a café in which there are haraam things?
Question

                What is the ruling on the one whose profit comes from a café? Here I would like to explain a few things to you: 

1-     Using the satellite dish for nothing else but to show music video clips and football (soccer) matches.

2-     Playing dominoes and dice. The customers play on the basis that the loser will pay for the drinks of everyone else, or he will give some money to the winner, and the café will have a share of this money.

3-     Smoking arghilehs (“hubble bubbles”) on a large scale.

4-     Young men sitting to watch the women in the street, most of whom are uncovered and adorned (tabarruj).

5-     The people sitting in the café joke with one another in a bad way, using foul language.

 My question is: is the money that comes from the café mixed money? Can I eat from this wealth? I cannot find work. The café belongs to my father and he is the one who is running it.
Praise be to Allah.Using the 
    satellite dish in the manner described, smoking the arghileh, gambling, 
    using foul language and looking at adorned woman are all obviously haraam 
    actions. The sin is on the one who does them and on the one who helps him to 
    do that, or approves of it without denouncing it. Undoubtedly opening a café 
    in which these evil things are done is haraam, and the money that comes as a 
    result of these evil things or for enabling people to do them is also 
    haraam, because Allaah says (interpretation of the meaning): 
“Help you 
    one another in Al‑Birr and At‑Taqwa (virtue, righteousness and piety); but 
    do not help one another in sin and transgression. And fear Allaah. Verily, 
    Allaah is Severe in punishment”

    [al-Maa’idah 5:2]
“And it 
    has already been revealed to you in the Book (this Qur’aan) that when you 
    hear the Verses of Allaah being denied and mocked at, then sit not with 
    them, until they engage in a talk other than that; (but if you stayed with 
    them) certainly in that case you would be like them. Surely, Allaah will 
    collect the hypocrites and disbelievers all together in Hell”
[al-Nisa’ 
    4:140]
al-Qurtubi 
    (may Allaah have mercy on him)said: “then sit not with them, until they 
    engage in a talk other than that” means, other than kufr. “(but if 
    you stayed with them) certainly in that case you would be like them” 
    this indicates that it is obligatory to avoid keeping company with sinners 
    if they openly commit evil, because the one who does not avoid them is 
    approving of their actions, and approving of kufr is kufr. Allaah says: “(but 
    if you stayed with them) certainly in that case you would be like them” 
    so everyone who sits in a sinful gathering and does not denounce them, 
    shares the burden of sin equally with them. 
He should 
    denounce them if they speak of sin and commit sin. If he is not able to 
    denounce them then he should get up and leave, so that he will not be one of 
    those mentioned in this verse. End quote. 
And the 
    Prophet  (peace and blessings of Allaah be upon him) said: “When Allaah 
    forbids eating a thing, He also forbids its price.” Narrated by Ahmad and 
    Abu Dawood (3026); classed as saheeh by al-Albaani in Saheeh 
    al-Jaami’, no. 5107.

If the loser 
    is required to pay money to the winner or buy drinks, this is undoubtedly a 
    kind of gambling. See question no.

Secondly: 
If your 
    father has another source of income, or in the café there are things that it 
    is permissible to sell, such as tea, coffee and so on, then your father’s 
    wealth is a mixture of halaal and haraam. In that case there is no sin on 
    you for eating from that wealth, so long as you need to, but it is better 
    not to. 
It says in
    Haashiyat al-Dasooqi (2/277): Note that if most of a person’s wealth 
    is halaal and a small part of it is haraam, then it is permissible to deal 
    with him and borrow money from him and eat from his wealth… but if most of 
    his wealth is haraam and a small part of it is halaal, then it is makrooh to 
    deal with him, borrow money from him and eat from his wealth. 
But if all 
    of his wealth is haraam, in that case it is not allowed to deal with him and 
    he should not be allowed to handle money or anything.  End quote. 
Shaykh Ibn 
    ‘Uthaymeen (may Allaah have mercy on him) said: If the father’s earnings are 
    haraam, then it is essential to advise him. Either advise him yourselves, if 
    you can, or seek the help of knowledgeable people who can convince him, or 
    seek the help of his friends who may convince him to avoid this haraam 
    earning. If that is not possible, then you can eat as much as is necessary, 
    and there is no sin on you in that case, but you should not take more than 
    you need, because there is some doubt about eating from one whose income is 
    haraam. End quote from Fataawa Islamiyyah (3/452).

We ask 
    Allaah to guide your father and set his affairs straight, and to grant you a 
    halaal and blessed provision. 
And Allaah 
    knows best.
