"Two will never be gathered together in the Fire: A Muslim who killed a disbeliever then tried his best and did not deviate. And two will never be gathered together in the lungs of a believer: Dust in the cause of Allah, and the odor of Hell. And two will never be gathered in the heart of a salve: Faith and envy."
أَخْبَرَنِي عِيسَى بْنُ حَمَّادٍ قَالَ أَخْبَرَنَا اللَّيْثُ عَنِ ابْنِ عَجْلَانَ عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «لَا يَجْتَمِعَانِ فِي النَّارِ مُسْلِمٌ قَتَلَ كَافِرًا ثُمَّ سَدَّدَ وَقَارَبَ وَلَا يَجْتَمِعَانِ فِي جَوْفِ مُؤْمِنٍ غُبَارٌ فِي سَبِيلِ اللهِ وَفَيْحُ جَهَنَّمَ وَلَا يَجْتَمِعَانِ فِي قَلْبِ عَبْدٍ الْإِيمَانُ وَالْحَسَدُ»
