Some of our friends have said that it is farz on her and on my husband as
her mehram and guardian to see to it.

As she doesn’t have any mahram except her father, she has to go with him if he is capable.

Regarding Haj, is it farz on my daughter age 17years as we are now living in Riyadh since past few months and have performed umrah. I and my husband did Haj some years back.
