Is celebrating a job promotion or a academic milestone permissible my family every time I might graduate or get good grades or get a job upgrade or promotion they like to celebrate with a party good food cake there’s no free mixing or Haram in that sense. I’m just scared that it’s an innovation?

Ustadh AbdulAziz al-Haqqan
It is lovely may Allah reward them for all that love, care, and joy for one another.
