I am doing a course for someone,  the whole course.  Is this a major or a minor sin ?   I already repented but still completeing the course for them,  do I need to repent again or what do I need to do?  They paid money for this.  Is the money haraam,  should I give to charity?  
 
Thanks very much,
Izzat!
