Ruling on being forced to shave one’s beard for those who work in the army
Question

                I am in the army and I always shave my beard, because I am forced to do so. Is this haraam or not?
Praise be to Allah.It is not permissible to shave the beard, because according 
          to saheeh ahaadeeth, the Messenger  
          (peace and blessings of Allaah be upon him) commanded us to leave it 
          alone and let it grow. He  (peace 
          and blessings of Allaah be upon him) told us that by leaving it alone 
          and letting it grow, we would be differing from the Magians and mushrikeen, 
          and he  (peace and blessings of 
          Allaah be upon him) had a thick beard. It is obligatory for us to obey 
          the Messenger  (peace and blessings 
          of Allaah be upon him); following his example with regard to attitude 
          and actions is one of the best deeds, because Allaah says (interpretation 
          of the meaning): 
“Indeed in the Messenger of Allaah 
          (Muhammad) you have a good example to follow [al-Ahzaab 33:21] 
“And whatsoever the Messenger 
          (Muhammad) gives you, take it; and whatsoever he forbids you, abstain 
          (from it) [al-Hashr :7] 
“And let those who oppose 
          the Messenger’s (Muhammad’s) commandment (i.e. his Sunnah  legal 
          ways, orders, acts of worship, statements) (among the sects) beware, 
          lest some Fitnah (disbelief, trials, afflictions, earthquakes, killing, 
          overpowered by a tyrant) should befall them or a painful torment be 
          inflicted on them  [al-Noor 
          24:63]  
Imitating the kuffaar is one of the gravest of evil actions, 
          and is one of the causes of being gathered with them on the Day of Resurrection, 
          because the Prophet  (peace and 
          blessings of Allaah be upon him) said, “Whoever imitates a people is 
          one of them.” If you are doing a job where you are required to shave 
          your beard, do not obey them with regard to that, because the Messenger 
           (peace and blessings of Allaah 
          be upon him) said, “There is no obedience to any created being if it 
          involves disobedience to the Creator.”  If they oblige you to shave 
          your beard, then leave that job where you are being forced to do something 
          that angers Allaah. There are many other ways of earning a living, may 
          Allaah be praised. Whoever gives up something for the sake of Allaah, 
          Allaah will compensate him with something better than that.  
May Allaah help you and make things easier for you. May 
          He make us and you steadfast in His religion.

          Allaah have mercy on him), vol. 8, p. 376  
But if your military 
          service is obligatory and they take you by force and shave your beard, 
          then the sin is on them and not on you at all. And Allaah knows best.
