that the Messenger of Allah ﷺ said: "The Fire complained to its Lord. It said: 'Some parts of me consume other parts.' So He allowed it to take two breaths: one during the winter, and during the summer. As for the breath in the winter then it is Zamharir, and as for the breath in the summer then it is Samum. Other chains report similar narrations.  

قَالَ رَسُولُ اللَّهِ ﷺ اشْتَكَتِ النَّارُ إِلَى رَبِّهَا وَقَالَتْ أَكَلَ بَعْضِي بَعْضًا فَجَعَلَ لَهَا نَفَسَيْنِ نَفَسًا فِي الشِّتَاءِ وَنَفَسًا فِي الصَّيْفِ فَأَمَّا نَفَسُهَا فِي الشِّتَاءِ فَزَمْهَرِيرٌ وَأَمَّا نَفَسُهَا فِي الصَّيْفِ فَسَمُومٌ  

“Some will exit the Fire,” Shuʿbah (another narrator) narrated it: 'Remove from the Fire whoever said La ilaha illallah and had good in his heart equal to the weight of a grain of barley. Remove from the Fire anyone who said La Ilaha illallah and had good in his heart equal to the weight of a grain of wheat. Remove from the Fire anyone who said La ilaha illallah and had good in his heart equal to the weight of a speck.” And Shubah said: “What is equal to the weight of a light piece of corn.” (Sahih) Other chains report similar narrations.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ قَالَ هِشَامٌ يَخْرُجُ مِنَ النَّارِ وَقَالَ شُعْبَةُ أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَكَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ شَعِيرَةً أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَكَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ بُرَّةً أَخْرِجُوا مِنَ النَّارِ مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَكَانَ فِي قَلْبِهِ مِنَ الْخَيْرِ مَا يَزِنُ ذَرَّةً وَقَالَ شُعْبَةُ مَا يَزِنُ ذُرَةً مُخَفَّفَةً وَفِي الْبَابِ عَنْ جَابِرٍ وَعِمْرَانَ بْنِ حُصَيْنٍ  

"Allah will say: 'Remove from the Fire whoever remembered Me one day, or feared Me while in a state of sinning."  

عَنِ النَّبِيِّ ﷺ قَالَ يَقُولُ اللَّهُ أَخْرِجُوا مِنَ النَّارِ مَنْ ذَكَرَنِي يَوْمًا أَوْ خَافَنِي فِي مَقَامٍ قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ
