Mixed farewell parties
Question

                What is the ruling on farewell parties where there is free mixing among the sexes? What is the ruling on healing through music?
Praise be to Allah. 
          Parties should not be mixed; it is necessary 
          for there to be parties for men only and parties for women only. Mixing 
          is an evil action and is one of the ways of the people of jaahiliyyah 
          (ignorance) – we seek refuge with Allaah from that.  
 
          With regard to healing through music, 
          there is no basis for that, rather it is the action of the foolish. 
          Music is not a healing, rather it is a disease and is based on the use 
          of forbidden (musical) instruments. All of that is a disease of the 
          heart and a cause for deviation of morals. The beneficial treatment 
          which will bring peace to the soul is for the patient to listen to the 
          Qur’aan and useful speeches and sermons. Treatment with music and the 
          like is something which makes people get used to falsehood and makes 
          them more sick, and makes them listen to the Qur’aan and Sunnah and 
          useful preaching even less. There is no strength and no power except 
          with Allaah.
