What attitude should children have for their stepmother?

Answer

Your ex-wife is a shaitaanah. The children must respect their stepmother. They have to respect her just as they respect their own mother. They may meet and visit her although the baaligh males should not be alone with her. The ex-wife is acting satanically. The stepmother is their father's 'best' friend, and regarding this, Rasulullah (Sallallahu alayhi wasallam) said:

"Of the best of good deeds is that a man is kind to the Family of the friends of his father after his (the father's) death."

In relation to the stepmother, the 'family of the friends of his father, is extremely distant. But Rasulullah (Sallallahu alayhi wasallam) described service to such distant friends of his father to be among the noblest deeds of virtue. Now, reflect and understand the value of the stepmother.
