What is the ruling on translating advertisements or invitations for musical concerts or similar events, knowing that this happens only rarely?

It is permissible to work for this company on the condition that you do not commit a sin or assist in one, for Allah Almighty says: (And cooperate in righteousness and piety, but do not cooperate in sin and aggression). Therefore, it is not permissible to translate advertisements or invitations that call for disobedience to Allah. If the company accepts this condition, then good; otherwise, seek another job, for Allah has decreed provisions and guaranteed them for those who fear Him and rely upon Him.
