عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ لَا يَجْتَمِعَانِ فِي النَّارِ اجْتِمَاعًا يَضُرُّ أَحَدَهُمَا مُسْلِمٌ قَتَلَ كَافِرًا ثُمَّ سَدَّدَ الْمُسْلِمُ أَوْ قَارَبَ وَلَا يَجْتَمِعَانِ فِي جَوْفِ عَبْدٍ غُبَارٌ فِي سَبِيلِ اللَّهِ وَدُخَانُ جَهَنَّمَ وَلَا يَجْتَمِعَانِ فِي قَلْبِ عَبْدٍ الْإِيمَانُ وَالشُّحُّ
Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Two men cannot be gathered together in the Fire in such a way that one of them is harmed; that Muslim who kills a disbeliever and then continues on the path of righteousness and adopts moderation. Two things cannot be gathered in a servant’s stomach: the dust from the path of Allah and the smoke of Hell. Two things cannot be gathered in a man’s heart: faith and greed.
