Assalamoalikum Mufti Sab,
Please reanswer the question that was asked by me not by my wife.
بسم اللہ الرحمن الرحیم
الجواب وباللہ التوفیق
It is not right to divorce her merely on the basis of your wife’s affiliation with Jamaat-e-Ahl-e-Hadith. Don't pay any attention to those thoughts.
Humbly, review those differences with your wife and address any doubts she has, after finding out appropriate answers from Ahl-e-Haqq and knowledgeable Ulemaa.
Try to avoid yourself being misled theoretically and intellectually.
