I told u its done secret SOMETIMES so first wife don't go into shock - "hey I found a 20 year old girl u knw so and so? Ya, his daughter. I have my nikkah with her fri u can come." Doesn't sound too good. But "hey r u happy?" "Of course I am ure the best husband." "Ok well for the past year I had 2nd wife, u know so and so? Ya, his daughter." Its easier to deal with. Ijazat not needed itteyla is needed.
