Should he obey his father and shave people’s beards in his shop?
Question

                I work in a barber shop, and this shop is owned by my father. I have a brother whom Allaah has blessed with guidance and he works with me in the shop. Now he is married and he is refusing to shave the customers’ beards because he thinks that this is forbidden in Islam, and that the money that he gets for shaving beards is haraam. I am single and am still living with my father. I used to refuse to shave customers’ beards at first, but my father put pressure on me and closed the shop. I do not have any other work My brother who insists on not shaving people’s beards is not suffering any pressure from my father because he lives in a different house, but I have the burden of preparing myself for marriage and I have some debts that I am paying off in instalments, so I went back to shaving beards, even though I hate it, so that my father would open the shop again. What should I do?.
Praise be to Allah.In the 
    answer to question no. 1190 and 
    8196 we have explained that it is haraam to 
    shave the beard and that it is haraam to help someone else to do so, whether 
    that is by opening a shop for shaving beards or otherwise. 
Obeying and 
    honouring one’s parents is obligatory, but there is no obedience to any 
    created being if it involves disobedience towards the Creator, as the 
    Prophet  (peace and blessings of Allaah be upon him) said: “There is no 
    obedience if it involves disobedience towards Allaah.” Narrated by 
    al-Bukhaari (6830) and Muslim (1840). Based on this, it is not permissible 
    to open a shop for shaving beards. You could limit yourself to shaving 
    heads, cutting hair and trimming moustaches, without touching people’s 
    beards. In this way you can combine two things: opening the shop and not 
    falling into haraam. 
Your father 
    should realize that earning a living must be done in accordance with 
    sharee’ah, and that Allaah will bless a small amount of halaal income 
    whereas He will erase the blessing from a large amount of haraam. You are 
    not required by sharee’ah to fall into this sin, and obedience to your 
    father is not binding in cases where that involves sin. 
Seek the 
    help of Allaah and do not respond to what your father is calling you to do. 
    Look for another job, or stay where you are, without shaving beards, and you 
    will be given a way out, and you will be granted provision from (sources) 
    you could never imagine, as Allaah says (interpretation of the meaning): 
“And 
    whosoever fears Allaah and keeps his duty to Him, He will make a way for him 
    to get out (from every difficulty).
3. And He 
    will provide him from (sources) he never could imagine. And whosoever puts 
    his trust in Allaah, then He will suffice him. Verily, Allaah will 
    accomplish his purpose. Indeed Allaah has set a measure for all things”
    [al-Talaaq 65:2-3]
Follow the 
    example of the best of generations, the companions of the Prophet  
    (peace and blessings of Allaah be upon him), who never put their worldly 
    interests before their religious commitment, or any worldly gain before the 
    goodness of the Hereafter. They would hear the Revelation forbidding them to 
    do something that was dear to their hearts, but they would hasten to give it 
    up. And they would hear a command that was burdensome for them, but they 
    would hasten to do it. The people of Madeenah were farmers, and they found 
    great benefit in some of their contracts, but when some of those contracts 
    were forbidden to them, one of them said: “The Messenger of Allaah  
    (peace and blessings of Allaah be upon him) has forbidden to us something 
    that was beneficial for us, but obedience to Allaah and His Messenger is 
    more beneficial for us.” Narrated by al-Bukhaari (2214) and Muslim (1548). 
When alcohol 
    was forbidden to the Sahaabah, they did not hesitate to stop drinking it, 
    even if the cup was in their hands, and they did not hesitate to break the 
    jars, rather they hastened to do that. It was narrated that Anas ibn Maalik 
    (may Allaah be pleased with him) said: I was pouring date wine made from 
    dried dates for Abu ‘Ubaydah ibn al-Jarraah, Abu Talhah and Ubayy ibn Ka’b, 
    when someone came to them and said: Khamr has been forbidden. Abu Talhah 
    said: O Anas, go to this pitcher and break it. So I went and got a pointed 
    stone of ours and I struck the lower part of it, until I broke it. Narrated 
    by al-Bukhaari(6826) and Muslim(1980). 
By means of 
    this attitude the early generation attained a level that could not be 
    attained by those who came after them. So the Muslim should not hesitate to 
    give up anything that he is doing that goes against Islam. He should 
    understand that this is what is required by the faith that he has accepted 
    for himself. Allaah says (interpretation of the meaning): 
“It is 
    not for a believer, man or woman, when Allaah and His Messenger have decreed 
    a matter that they should have any option in their decision. And whoever 
    disobeys Allaah and His Messenger, he has indeed strayed into a plain error”

    [al-Ahzaab 33:36]
And Allaah 
    knows best.
