17:101
وَلَقَدْ ءَاتَيْنَا مُوسَىٰ تِسْعَ ءَايَٰتٍۭ بَيِّنَٰتٍۢ ۖ فَسْـَٔلْ بَنِىٓ إِسْرَٰٓءِيلَ إِذْ جَآءَهُمْ فَقَالَ لَهُۥ فِرْعَوْنُ إِنِّى لَأَظُنُّكَ يَٰمُوسَىٰ مَسْحُورًۭا
And We had certainly given Moses nine evident signs, so ask the Children of Israel [about] when he came to them and Pharaoh said to him, "Indeed I think, O Moses, that you are affected by magic."

("O Musa! I think you are indeed bewitched. ") It was said that this meant he thought he was a sorcerer, but Allah knows best. These nine signs which were mentioned by the Imams (scholars) quoted above are what is referred to here, and in the Ayah :
