How shall we save our family members from Hell?

It is stated in Khazain-ul-Irfaan with regard to the forgoing
verse, “(save yourselves and your families from the fire of Hell)
by obeying Allah and His beloved Prophetsallallahu alaihi wasallam,
performing worship, refraining from sins, guiding your families
towards goodness and forbidding them from evils and by
teaching them knowledge & etiquettes.”
