Praise be to Allah.We
      put this question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen, may
      Allaah preserve him, who answered as follows:
 If
      he is going to give it to you on the basis that it is diyah (blood money),
      then you should not take it, because he is a kaafir and you are a Muslim;
      a Muslim cannot inherit from a kaafir, and diyah is a kind of inheritance.
      If he is going to give it to you just to make you feel better (as a gift),
      then there is nothing wrong with taking it. And Allaah knows best.
