﴿ قُلْنَا يَٰنَارُ كُونِى بَرْدًۭا وَسَلَٰمًا عَلَىٰٓ إِبْرَٰهِيمَ ﴾

“[But] We said: O fire! Be thou cool, and [a source of] inner peace for Abraham!””

(We said: O fire, be coolness) against your heat (and peace) and safety from your coolness (for Abraham) for if Allah did not say " peace " the coolness of the Fire would have harmed him.
