Sunan an-Nasa'i, Volume 4, Book 25, Hadith 3111 (DarusSalam) ⓘ

It was narrated from Abu Hurairah that The Messenger of Allah said: "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."

أَخْبَرَنَا عِيسَى بْنُ حَمَّادٍ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ عَجْلاَنَ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ يَجْتَمِعَانِ فِي النَّارِ مُسْلِمٌ قَتَلَ كَافِرًا ثُمَّ سَدَّدَ وَقَارَبَ وَلاَ يَجْتَمِعَانِ فِي جَوْفِ مُؤْمِنٍ غُبَارٌ فِي سَبِيلِ اللَّهِ وَفَيْحُ جَهَنَّمَ وَلاَ يَجْتَمِعَانِ فِي قَلْبِ عَبْدٍ الإِيمَانُ وَالْحَسَدُ ‏" ‏ ‏.‏
