وَدَخَلَ ٱلْمَدِينَةَ عَلَىٰ حِينِ غَفْلَةٍ 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 عَدُوٌّ مُّضِلٌّ مُّبِينٌ

He said: This is on account of the Shaitan’s doing; surely he is an enemy, openly leading astray.
