Do you want to know a dua to say during Winter? It may come as a surprise to many that Jahannam also has a cold area.
The following are more than enough to convince us of this phenomenon: Sayyiduna Abu Hurayrah رضي الله عنه reported that Rasulullah صلى الله عليه وسلم said, “Jahannam complained to its Rabb saying: ‘Oh my Lord, Parts within me have devoured each other.’ So Allah allowed it two breaths: one in summer and the other in winter.
Therefore the extreme heat that you experience (on earth) is caused by the heat of Jahannam and the severe cold too is due to the al-zamharīr (the extremely cold section of Jahannam).” (Sahīh Bukhārī Hadith 537, Sahīh Muslim)
Rasulullah (saw) is reported to have said: ” When a person recites this supplication, Almighty Allah says to Jahannam: “Verily a servant of mine has sought refuge in me from you, bear testimony that I have granted him salvation from you”
لا ِاله ِالا اللهُ مَآ أشَدَّ بَرْدَ هذا الْيَوْمْ ، اَللّٰهُمَّ أجِرْنِيْ مِنْ زَمْهَرِيْرِجَهَنَّمْ
Laa ilaaha illallahu ma ashadda barda hazhal yawm , allahumma ajirni min zamhareeri jahannam.
“There is no deity but Allah, How severe is the cold of today! O Allah! Protect me from the severe cold of Jahannam” (Ibnu Sunni # 30) ( رواه ابن السني –– )
