عَنْ أَبِي أَيُّوبَ الْأَنْصَارِيِّ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَنْ جَاءَ يَعْبُدُ اللَّهَ لَا يُشْرِكُ بِهِ شَيْئًا وَيُقِيمُ الصَّلَاةَ وَيُؤْتِي الزَّكَاةَ وَيَصُومُ رَمَضَانَ وَيَجْتَنِبُ الْكَبَائِرَ فَإِنَّ لَهُ الْجَنَّةَ وَسَأَلُوهُ مَا الْكَبَائِرُ قَالَ الْإِشْرَاكُ بِاللَّهِ وَقَتْلُ النَّفْسِ الْمُسْلِمَةِ وَفِرَارٌ يَوْمَ الزَّحْفِ
It is narrated from Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever comes (to Allah) in such a state that he has not associated anyone with Allah, established prayer, paid zakat, fasted in Ramadan, and avoided major sins, then Paradise will be for him. Then the people asked the Prophet (peace and blessings be upon him) about the major sins, and he (peace and blessings be upon him) said: Associating partners with Allah, killing a Muslim soul, and fleeing on the day of battle.
