Salam aleikum,
I have a question regarding the validity of adding conditions in a marriage contract. From my understanding, having conditions is permissible if the rights of both parties are respected. However, I was in the process of getting engaged to someone after two years together but he did not know this was permissible and viewed it as a breach of trust. He has since terminated the relationship as he believed that I did not trust him whereas I viewed having conditions as a source of protection and accountability.
My question is, is having stipulations in a marriage contract a cultural norm or does it have religious validity. If it is based in Islam, would it be possible to receive concrete facts on its validity from the Qu'ran or the Hadiths?
Thank you very much for your help and insights!
