Abu Huraira reported: The Prophet, peace and blessings be upon him, said, “Stay away from seven mortal sins.” They said, “O Messenger of Allah, what are they?” The Prophet said, “Idolatry with Allah, occult magic, killing a soul that Allah has sanctified except for a just cause, consuming usury, usurping the property of an orphan, fleeing the battlefield, and accusing chaste but unwary believing women.”

عَنْ أَبِي هُرَيْرَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ اجْتَنِبُوا السَّبْعَ الْمُوبِقَاتِ قَالُوا يَا رَسُولَ اللَّهِ وَمَا هُنَّ قَالَ الشِّرْكُ بِاللَّهِ وَالسِّحْرُ وَقَتْلُ النَّفْسِ الَّتِي حَرَّمَ اللَّهُ إِلَّا بِالْحَقِّ وَأَكْلُ الرِّبَا وَأَكْلُ مَالِ الْيَتِيمِ وَالتَّوَلِّي يَوْمَ الزَّحْفِ وَقَذْفُ الْمُحْصَنَاتِ الْمُؤْمِنَاتِ الْغَافِلَاتِ
