Here’s a couplet on family salvation in Urdu (I believe the Lord gave it to me):
Hazaaro Aaftab se Badhkar Roshni Laai Hai; (x2)
Aaj Hamaare Gharaane ne Najaat Paai Hai
Translated, it means:
Brightness Exceeding A Thousand Suns Has It Brought;
Today Salvation Has Our Household Got
If you are praying for the salvation of your family members, you can take inspiration from the above couplet. They say that if you do what you have always done, you will get what you have always got. So if you keep asking God for their salvation, it means you are operating from a position of “family not saved.” Rather, if you begin thanking the Lord for their salvation, you acknowledge that you trust God’s willingness to save your family/household.
