Muslim man marrying a Qadiani (Ahmadi) woman who
    is of good character
Question

                I understand that ist alright for
      a Muslim male to marry a woman from the people of the book. But how about if a Muslim male
      wants to marry a Qadiani girl, who's of a good character and personality?
Praise be to Allah.Given that the Qadiani school of thought is a form 
  of major Kufr (disbelief) which puts them beyond the pale of Islam [i.e., Qadianis 
  are not Muslims  see Question 4060], 
  it is not permissible to marry this woman, because Allaah says (interpretation 
  of the meaning):
They are not lawful (wives) for the disbelievers 
  nor are the disbelievers lawful (husbands) for them [al-Mumtahinah 60:10] 

And Allaah knows best.
