Sunan an-Nasai
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا بَقِيَّةُ، قَالَ حَدَّثَنِي بَحِيرُ بْنُ سَعْدٍ، عَنْ خَالِدِ بْنِ مَعْدَانَ، أَنَّ أَبَا رُهْمٍ السَّمَعِيَّ، حَدَّثَهُمْ أَنَّ أَبَا أَيُّوبَ الأَنْصَارِيَّ حَدَّثَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ جَاءَ يَعْبُدُ اللَّهَ وَلاَ يُشْرِكُ بِهِ شَيْئًا وَيُقِيمُ الصَّلاَةَ وَيُؤْتِي الزَّكَاةَ وَيَجْتَنِبُ الْكَبَائِرَ كَانَ لَهُ الْجَنَّةُ " . فَسَأَلُوهُ عَنِ الْكَبَائِرِ فَقَالَ " الإِشْرَاكُ بِاللَّهِ وَقَتْلُ النَّفْسِ الْمُسْلِمَةِ وَالْفِرَارُ يَوْمَ الزَّحْفِ " .
Abu Ayyub Al-Ansari narrated that: The Messenger of Allah [SAW] said: "Whoever comes worshipping Allah and not associating anything with Him, establishing Salah, paying Zakah and avoiding major sins, Paradise will be his." They asked him about major sins and he said: "Associating others with Allah, killing a Muslim soul, and fleeing (from the battlefield) on the day of the march."
