Al-Qasas 28:15
وَدَخَلَ الْمَدِينَةَ عَلَىٰ حِينِ غَفْلَةٍ مِّنْ أَهْلِهَا فَوَجَدَ فِيهَا رَجُلَيْنِ يَقْتَتِلَانِ هَٰذَا مِن شِيعَتِهِ وَهَٰذَا مِنْ عَدُوِّهِ ۖ فَاسْتَغَاثَهُ الَّذِي مِن شِيعَتِهِ عَلَى الَّذِي مِنْ عَدُوِّهِ فَوَكَزَهُ مُوسَىٰ فَقَضَىٰ عَلَيْهِ ۖ قَالَ هَٰذَا مِنْ عَمَلِ الشَّيْطَانِ ۖ إِنَّهُ عَدُوٌّ مُّضِلٌّ مُّبِينٌ ١٥

And Musa (Moses) entered the city (in Egypt) at a time when its people were lying (asleep) unaware. There he found two men fighting with each other, one from his (own) party (the Children of Israel), and the other from his enemies (the people of Pharaoh). The man from his own party asked him for help against the other who was from his enemies. So Musa (Moses) struck him with his fist and killed him. (Then) he said: ‘This is Satan’s work (which I have committed); no doubt he is an open, misleading enemy.’ (28:15)
