The greatest rights of a suitor due upon his fiancée on her part are: exerting a serious effort in order to reach mutual understanding, strengthening ties of trust between each other by being honest in intimacy as well maintaining kind treatment, avoiding what might cause him harm and curb his happiness, reminding him to be keen on the fear of Allah, The Exalted and assuming good intention at the beginning of forming the happy Islamic family. And Allah Knows Best.
