save yourselves and your families from a fire whose fuel is men and stones, over which are (appointed) angels, stern (and) severe,

"O you who have believed, save yourselves and your families from a fire whose fuel is men and stones, over which are (appointed) angels, stern (and) severe, who do not disobey Allah in what He orders them and (who) do (precisely) what they are commanded."
[Qur'an, Surah At-Tahrim 66 -6]
