So I performed my umrah e Mufradah, bore all restrictions of ihram. Performed it in the right order. But there is one problem that happened. I prayed my tawaf prayers (at the station of ibrahim (A.S) ) and tawaf un nissa prayers with hands closed (like sunni’s pray) as my family is rigid sunni and they would know or doubt me if i prayed with my hands open. Is my umrah complete? Because there is no way that I could have performed those 2 prayers with my hands open. Do I have any kaffara on my head?

It is ok if you had no choice. However you can do qadha of the namaz later when your family is not around. You have to do qadha and pray the namaz the normal way
