what is meaning of tehzeeb(hope i spelled it r8)
Tehzeeb is derived from Arabic and it literally means "trimming or cutting out the bad, harmful, useless, obscene parts of the looks, speech, behavior etc". However, the context in which it is used in Qubool Hai means culturally well-mannered and disciplined. Simply put, "tehzeeb" is the proper display of manners & etiquettes that accompany the Muslim culture (& perhaps many others, just under a different name).
Hope I helped!
