Surah Al-Qasas, Verse 15
وَدَخَلَ ٱلْمَدِينَةَ عَلَىٰ حِينِ غَفْلَةٍۢ مِّنْ أَهْلِهَا فَوَجَدَ فِيهَا رَجُلَيْنِ يَقْتَتِلَانِ هَٰذَا مِن شِيعَتِهِۦ وَهَٰذَا مِنْ عَدُوِّهِۦ ۖ فَٱسْتَغَٰثَهُ ٱلَّذِى مِن شِيعَتِهِۦ عَلَى ٱلَّذِى مِنْ عَدُوِّهِۦ فَوَكَزَهُۥ مُوسَىٰ فَقَضَىٰ عَلَيْهِ ۖ قَالَ هَٰذَا مِنْ عَمَلِ ٱلشَّيْطَٰنِ ۖ إِنَّهُۥ عَدُوٌّۭ مُّضِلٌّۭ مُّبِينٌۭ
Translation — Sahih International
And he entered the city at a time of inattention by its people 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."
