You are allowed to get married to a Muslim following the Ja’fari Madhhab. However, marriage is long-term commitment and partnership. Since there are differences between certain beliefs and practices of Ahl Al-Sunnah and the Shi`ah, you should only be willing to tie the knot after you have figured out how to deal with the differences in an amicable way. It is not realistic to say that we would sort it out later.

So, I urge you to have all the points at stake and come up with a balanced and amicable way of dealing with the differences. You should stipulate that both of you should be able to follow your respective madhhabs without sacrificing the marriage relationship.

Once you have agreed upon the salient points, you should sign a contract to that effect. There is a saying, sometimes attributed to Prophet (peace be upon him) “There is no intelligence greater than planning.”

May Allah bless you in your decision and give you success, amen.

Allah Almighty knows best.
