“The Fire complained to its Lord and said: ‘O Lord, parts of me
have consumed other parts.’ So He gave it two occasions to exhale,
one
in winter and one in summer. The intense cold that you feel (in
winter) is part of its severe frost (Zamharir) and the intense heat
that you feel in summer is part of its hot wind (Samum).”
Sunan Ibn Majah Book 37, Hadith 220
