Listening
      to music when one is put on hold
Question

                My
      Muslim brother asks: "At my job site the disbelievers play music over
      the intercom. I want to know whether I am responsible for this. Insha
      Allah!"
Praise be to Allah.If you have the choice and are able to remove this evil, 
  then do so. If the matter is beyond your control, then you will not be held 
  accountable, so long as you do not deliberately listen and enjoy that, because 
  music is haraam (see Question #5011). 
  The same applies to singing, because Allaah says (interpretation of the meaning):
“And 
  of mankind is he who purchases idle talks (i.e. music, singing) to mislead (men) 
  from the path of Allaah without knowledge…” [Luqmaan 31:6]
Ibn Mas’ood said: 
  This refers to singing. Similar views were narrated from others among the Sahaabah 
  (may Allaah be pleased with them all) and the Salaf. Shaykh al-Islam (Ibn Taymiyah) 
  differentiated between listening for the purpose of enjoyment enjoyment, and 
  unintentional hearing where one has no choice in the matter. In the latter case 
  there is no blame or sin involved, and Allaah does not burden a soul beyond 
  its scope. If the other party puts you on hold on the phone, then try not to 
  listen to the music as much as possible. Beware of actively enjoying the music, 
  and seek the forgiveness of Allaah, for Allaah is Oft-Forgiving, Most Merciful.
