Sahih al-Bukhari, Hadith 6857 ⓘ

Narrated Abu Huraira: The Prophet said, "Avoid the seven great destructive sins." They (the people!) asked, "O Allah's Apostle! What are they?" He said, "To join partners in worship with Allah; to practice sorcery; to kill the life which Allah has forbidden except for a just cause (according to Islamic law); to eat up usury (Riba), to eat up the property of an orphan; to give one's back to the enemy and fleeing from the battle-field at the time of fighting and to accuse chaste women who never even think of anything touching chastity and are good believers."

حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُلَيْمَانُ، عَنْ ثَوْرِ بْنِ زَيْدٍ، عَنْ أَبِي الْغَيْثِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ اجْتَنِبُوا السَّبْعَ الْمُوبِقَاتِ ‏"‏‏.‏ قَالُوا يَا رَسُولَ اللَّهِ وَمَا هُنَّ قَالَ ‏"‏ الشِّرْكُ بِاللَّهِ، وَالسِّحْرُ، وَقَتْلُ النَّفْسِ الَّتِي حَرَّمَ اللَّهُ إِلاَّ بِالْحَقِّ، وَأَكْلُ الرِّبَا، وَأَكْلُ مَالِ الْيَتِيمِ، وَالتَّوَلِّي يَوْمَ الزَّحْفِ، وَقَذْفُ الْمُحْصَنَاتِ الْمُؤْمِنَاتِ الْغَافِلاَتِ ‏"‏‏.‏
