Sihr, and the half that gets dropped
Sihr is real in the text. That is not in dispute and this course is not shading it. The verse about Harut and Marut affirms it, and Bukhari reports that it was worked on the Prophet himself, peace be upon him, by Labid bin al-A'sam.
Now read the rest of the same verse, which is the half that gets left out of the telling. They harm nobody except by the permission of Allah. And when Musa faced the magicians, the Qur'an says Allah will nullify it.
Qur’an and Sunnah
فَلَمَّآ أَلۡقَوۡاْ قَالَ مُوسَىٰ مَا جِئۡتُم بِهِ ٱلسِّحۡرُۖ إِنَّ ٱللَّهَ سَيُبۡطِلُهُۥٓ إِنَّ ٱللَّهَ لَا يُصۡلِحُ عَمَلَ ٱلۡمُفۡسِدِينَ
When they did so, Moses said, ‘Everything you have brought is sorcery and God will show it to be false. God does not make the work of mischief-makers right
Qur’an 10:81
وَٱتَّبَعُواْ مَا تَتۡلُواْ ٱلشَّيَٰطِينُ عَلَىٰ مُلۡكِ سُلَيۡمَٰنَۖ وَمَا كَفَرَ سُلَيۡمَٰنُ وَلَٰكِنَّ ٱلشَّيَٰطِينَ كَفَرُواْ يُعَلِّمُونَ ٱلنَّاسَ ٱلسِّحۡرَ وَمَآ أُنزِلَ عَلَى ٱلۡمَلَكَيۡنِ بِبَابِلَ هَٰرُوتَ وَمَٰرُوتَۚ وَمَا يُعَلِّمَانِ مِنۡ أَحَدٍ حَتَّىٰ يَقُولَآ إِنَّمَا نَحۡنُ فِتۡنَةࣱ فَلَا تَكۡفُرۡۖ فَيَتَعَلَّمُونَ مِنۡهُمَا مَا يُفَرِّقُونَ بِهِۦ بَيۡنَ ٱلۡمَرۡءِ وَزَوۡجِهِۦۚ وَمَا هُم بِضَآرِّينَ بِهِۦ مِنۡ أَحَدٍ إِلَّا بِإِذۡنِ ٱللَّهِۚ وَيَتَعَلَّمُونَ مَا يَضُرُّهُمۡ وَلَا يَنفَعُهُمۡۚ وَلَقَدۡ عَلِمُواْ لَمَنِ ٱشۡتَرَىٰهُ مَا لَهُۥ فِي ٱلۡأٓخِرَةِ مِنۡ خَلَٰقࣲۚ وَلَبِئۡسَ مَا شَرَوۡاْ بِهِۦٓ أَنفُسَهُمۡۚ لَوۡ كَانُواْ يَعۡلَمُونَ
and followed what the evil ones had fabricated about the Kingdom of Solomon instead. Not that Solomon himself was a disbeliever; it was the evil ones who were disbelievers. They taught people witchcraft and what was revealed in Babylon to the two angels Harut and Marut. Yet these two never taught anyone without first warning him, ‘We are sent only to tempt- do not disbelieve.’ From these two, they learned what can cause discord between man and wife, although they harm no one with it except by God’s leave. They learned what harmed them, not what benefited them, knowing full well that whoever gained [this knowledge] would lose any share in the Hereafter. Evil indeed is the [price] for which they sold their souls, if only they knew
Qur’an 2:102
Narrated `Aisha:Magic was worked on Allah's Messenger (ﷺ) so that he began to imagine that he had done something although he had not. One day while he was with me, he invoked Allah and invoked for a long period and then said, "O `Aisha! Do you know that Allah has instructed me regarding the matter I asked Him about?" I asked, "What is that, O Allah's Messenger (ﷺ)?" He said, "Two men came to me; one of them sat near my head and the other sat near my feet. One of them asked his companion, 'What is the disease of this man?' The other replied, 'He is under the effect of magic.' The first one asked, 'Who has worked magic on him?" The other replied, 'Labid bin A'sam, a Jew from the tribe of Bani Zuraiq.' The (first one asked), 'With what has it been done?' The other replied, 'With a a comb and the hair stuck to it and a skin of the pollen of a male datepalm tree.' The first one asked, 'Where is it?' The other replied, 'In the well of Dharwan.' Then the Prophet (ﷺ) went along with some of his companions to that well and looked at that and there were date palms near to it. Then he returned to me and said, 'By Allah the water of that well was (red) like the infusion of Henna leaves and its date-palms were like the heads of devils" I said, O Allah's Messenger (ﷺ)! Did you take those materials out of the pollen skin?" He said, 'No! As for me Allah has healed me and cured me and I was afraid that (by Showing that to the people) I would spread evil among them when he ordered that the well be filled up with earth, and it was filled up with earth

Narrated `Aisha:A man called Labid bin al-A'sam from the tribe of Bani Zaraiq worked magic on Allah's Messenger (ﷺ) till Allah's Messenger (ﷺ) started imagining that he had done a thing that he had not really done. One day or one night he was with us, he invoked Allah and invoked for a long period, and then said, "O `Aisha! Do you know that Allah has instructed me concerning the matter I have asked him about? Two men came to me and one of them sat near my head and the other near my feet. One of them said to his companion, "What is the disease of this man?" The other replied, "He is under the effect of magic.' The first one asked, 'Who has worked the magic on him?' The other replied, "Labid bin Al-A'sam.' The first one asked, 'What material did he use?' The other replied, 'A comb and the hairs stuck to it and the skin of pollen of a male date palm.' The first one asked, 'Where is that?' The other replied, '(That is) in the well of Dharwan;' " So Allah's Messenger (ﷺ) along with some of his companions went there and came back saying, "O `Aisha, the color of its water is like the infusion of Henna leaves. The tops of the date-palm trees near it are like the heads of the devils." I asked. "O Allah's Messenger (ﷺ)? Why did you not show it (to the people)?" He said, "Since Allah cured me, I disliked to let evil spread among the people." Then he ordered that the well be filled up with earth
