سنن ابن ماجه

It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said: “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).”
