Quran 2, Al-Baqara (The Cow) ⓘ

2:102And follow that which the devils falsely related against the kingdom of Solomon. Solomon disbelieved not; but the devils disbelieved, teaching mankind magic and that which was revealed to the two angels in Babel, Harut and Marut. Nor did they (the two angels) teach it to anyone till they had said: We are only a temptation, therefore disbelieve not (in the guidance of Allah). And from these two (angles) people learn that by which they cause division between man and wife; but they injure thereby no-one save by Allah's leave. And they learn that which harmeth them and profiteth them not. And surely they do know that he who trafficketh therein will have no (happy) portion in the Hereafter; and surely evil is the price for which they sell their souls, if they but knew.

وَاتَّبَعُوا مَا تَتْلُو الشَّيَاطِينُ عَلَى مُلْكِ سُلَيْمَانَ وَمَا كَفَرَ سُلَيْمَانُ وَلَكِنَّ الشَّيَاطِينَ كَفَرُوا يُعَلِّمُونَ النَّاسَ السِّحْرَ وَمَا أُنْزِلَ عَلَى الْمَلَكَيْنِ بِبَابِلَ هَارُوتَ وَمَارُوتَ وَمَا يُعَلِّمَانِ مِنْ أَحَدٍ حَتَّى يَقُولَا إِنَّمَا نَحْنُ فِتْنَةٌ فَلَا تَكْفُرْ فَيَتَعَلَّمُونَ مِنْهُمَا مَا يُفَرِّقُونَ بِهِ بَيْنَ الْمَرْءِ وَزَوْجِهِ وَمَا هُمْ بِضَارِّينَ بِهِ مِنْ أَحَدٍ إِلَّا بِإِذْنِ اللَّهِ وَيَتَعَلَّمُونَ مَا يَضُرُّهُمْ وَلَا يَنْفَعُهُمْ وَلَقَدْ عَلِمُوا لَمَنِ اشْتَرَاهُ مَا لَهُ فِي الْآخِرَةِ مِنْ خَلَاقٍ وَلَبِئْسَ مَا شَرَوْا بِهِ أَنْفُسَهُمْ لَوْ كَانُوا يَعْلَمُونَ
