If a young woman has a womb problem, or problems in menstruation that necessitate medical treatment, something that might delay pregnancy, should her fiancé be told about that?
If this problem is a contingent problem that can happen to other women but clears away, there is no need to tell him about it. Whereas, if this problem is not a contingent problem, rather an effective one that (Part No. 19; Page No. 15) continues to persist during the engagement period, thereof, her guardian should tell her fiancé about it. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
