Read Ruku 13 of the Quran

وَٱتَّبَعُوا۟ مَا تَتْلُوا۟ ٱلشَّيَـٰطِينُ عَلَىٰ مُلْكِ سُلَيْمَـٰنَ ۖ وَمَا كَفَرَ سُلَيْمَـٰنُ وَلَـٰكِنَّ ٱلشَّيَـٰطِينَ كَفَرُوا۟ يُعَلِّمُونَ ٱلنَّاسَ ٱلسِّحْرَ وَمَآ أُنزِلَ عَلَى ٱلْمَلَكَيْنِ بِبَابِلَ هَـٰرُوتَ وَمَـٰرُوتَ ۚ وَمَا يُعَلِّمَانِ مِنْ أَحَدٍ حَتَّىٰ يَقُولَآ إِنَّمَا نَحْنُ فِتْنَةٌۭ فَلَا تَكْفُرْ ۖ فَيَتَعَلَّمُونَ مِنْهُمَا مَا يُفَرِّقُونَ بِهِۦ بَيْنَ ٱلْمَرْءِ وَزَوْجِهِۦ ۚ وَمَا هُم بِضَآرِّينَ بِهِۦ مِنْ أَحَدٍ إِلَّا بِإِذْنِ ٱللَّهِ ۚ وَيَتَعَلَّمُونَ مَا يَضُرُّهُمْ وَلَا يَنفَعُهُمْ ۚ وَلَقَدْ عَلِمُوا۟ لَمَنِ ٱشْتَرَىٰهُ مَا لَهُۥ فِى ٱلْـَٔاخِرَةِ مِنْ خَلَـٰقٍۢ ۚ وَلَبِئْسَ مَا شَرَوْا۟ بِهِۦٓ أَنفُسَهُمْ ۚ لَوْ كَانُوا۟ يَعْلَمُونَ ﴿١٠٢﴾

And they followed [instead] what the devils had recited during the reign of Solomon. It was not Solomon who disbelieved, but the devils disbelieved, teaching people magic and that which was revealed to the two angels at Babylon, Harut and Marut. But the two angels do not teach anyone unless they say, "We are a trial, so do not disbelieve [by practicing magic]." And [yet] they learn from them that by which they cause separation between a man and his wife. But they do not harm anyone through it except by permission of Allah. And the people learn what harms them and does not benefit them. But the Children of Israel certainly knew that whoever purchased the magic would not have in the Hereafter any share. And wretched is that for which they sold themselves, if they only knew.

وَلَوْ أَنَّهُمْ ءَامَنُوا۟ وَٱتَّقَوْا۟ لَمَثُوبَةٌۭ مِّنْ عِندِ ٱللَّهِ خَيْرٌۭ ۖ لَّوْ كَانُوا۟ يَعْلَمُونَ ﴿١٠٣﴾

And if they had believed and feared Allah, then the reward from Allah would have been [far] better, if they only knew.
