O Believers! Save yourselves and your families (wife, children etc.) from a fire whose fuel is men and stones, over which are appointed stern and severe angels, who do not disobey Allah in that which He has commanded them and they do (precisely) what they have been commanded. (Surah TahreeM, Aayah 6)
Hadhrat Ali (Radhiallahu anhu) says that ‘save your families’ means that you should discipline them and give them proper Islamic education.
