Ibn al-Jawzi رحمه الله narrates to us:
“There was a king who had a lot of wealth, and he had a daughter and no other children. He loved her very much, and he used to let her enjoy all kinds of entertainment. This went on for a long time.

Beside the king there lived a devoted worshipper, and whilst he was reciting one night, he raised his voice saying, “O you who believe! Ward off yourselves and your families against a Fire (Hell) whose fuel is men and stones, over which are (appointed) angels stern (and) severe, who disobey not, (from executing) the Commands they receive from Allah, but do that which they are commanded” [Al-Tahrim 66:6].

The girl heard his recitation and said to her servants, “Stop!” But they did not stop. The worshipper started to repeat the verse, and the girl kept telling them to stop, but they did not stop. She put her hands to her collar and tore her garment, and they went to her father and told him the story.

He went to her and said, “My dear, what happened to you tonight? What made you weep?” and he hugged her. She said, “I ask you by Allah, O my father, to tell me, does Allah have a Fire the fuel of which is men and stones?”

He said, “Yes.” She asked him, “Why did you not tell me? By Allah I will not eat any good food or sleep on any soft bed until I know whether my abode is in Paradise or Hell.” (Safwat al-Safwah, 4/437-438)

Dear parents,
Part of your duty is to bring them up from a young age to love Allah and His Messenger and to love the teachings of Islam. You should tell them that Allah has a Paradise and a Hell; that His Hell is hot and its fuel is men and stones. This guidance must begin when they are young, as habits formed early are easier to sustain. By instilling good values and practices from a young age, it becomes simpler to guide them as they grow, for they will already be accustomed to obeying and understanding what is right and wrong.
