Surah Al-Qashash Ayah 15

وَدَخَلَ ٱلۡمَدِينَةَ عَلَىٰ حِينِ غَفۡلَةٖ مِّنۡ أَهۡلِهَا فَوَجَدَ فِيهَا رَجُلَيۡنِ يَقۡتَتِلَانِ هَٰذَا مِن شِيعَتِهِۦ وَهَٰذَا مِنۡ عَدُوِّهِۦۖ فَٱسۡتَغَٰثَهُ ٱلَّذِي مِن شِيعَتِهِۦ عَلَى ٱلَّذِي مِنۡ عَدُوِّهِۦ فَوَكَزَهُۥ مُوسَىٰ فَقَضَىٰ عَلَيۡهِۖ قَالَ هَٰذَا مِنۡ عَمَلِ ٱلشَّيۡطَٰنِۖ إِنَّهُۥ عَدُوّٞ مُّضِلّٞ مُّبِينٞ ١٥

And he entered the city at a time of inattention by its people¹ and found therein two men fighting: one from his faction and one from among his enemy. And the one from his faction called for help to him against the one from his enemy, so Moses struck him and [unintentionally] killed him. [Moses] said, "This is from the work of Satan. Indeed, he is a manifest, misleading enemy."
