Magic in Islam?

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. (Surah Baqarah Ayah 102)

In this verse of Surah Baqarah, Allah swt is narrating another act of disbelief committed by Bani Israel in the time, when Allah swt sent Suleman as a prophet to Bani Israel. Allah swt blessed Suleman as with the most powerful kingdom, which no one else was given. Even Jinns and animals were in his control. It was the time of great worldly advancement. Instead of recognizing the miracles/powers of Suleman A.S as the blessings of Allah swt, deviant Jews at that time considered Suleman A.S as a magician and started to believe that all his powers and miracles were due to magic. This is why they also got inclined to learning black magic and they used to go to satans (among humans and jinns) to learn black magic from them. 

To test them more, Allah swt, sent two angels, Harut and Marut, in Babylon. These angels taught magic to people with the permission of Allah swt but they always warned them (about the harmful consequences of learning it) before teaching them. But these warnings did not prevent them from learning magic. They learned magic to cause separation between husband and wife in order to create societal corruption. But their magic did not harm anyone except with the will of Allah swt. In this way, they sold their Imaan and akhirah for the petty worldly gains.

From this verse, we learned that:

1) When a nation disobeys Allah swt, Allah swt tests them through more temptations which are harder to resist. As Bani Israel refused to accept Suleman A.S as their prophet and found magic fascinating, Allah tested them through the two angels to show them that magic is indeed different from miracles given to Suleman A.S. So, whenever we feel tempted to commit a wrong action/sin, we should turn to Allah, do istighfaar as these evil temptations are punishment from Allah swt for disobeying Him.

2) Practicing or teaching black magic is major kufr/disbelief. So, we should stay from it completely. Subhanallah think about even though we do not practice magic, we are so much fascinated by it. Harry Potter, TV shows and movies based on vampires and witches; and fairy tales make us and our children desensitized to the evilness of magic. We are so much influenced by these shows, cartoons and movies that we don't even fully accept the sinful nature of magic shown in them. Therefore, we should seek Allah's help to remove the love of these from our heart.

3) No matter how strong the magic is, Allah swt is the most Powerful. If we seek protection from Allah through Ayatul Kursi, four quls, last two verses of surah baqarah and stay clean, inshAllah no magic can affect us. Remember, no one can harm us without the will of Allah swt. 
Unfortunately, in this time, we tend to blame every misfortune that befalls on us as an act of magic of our enemy. Ignorant Muslims seek protection from magic through magic. Instead of turning to Allah, the deviant Muslims turn to evil eye necklace and bracelets (ta'weedh). May Allah guide them, Ameen!
In order to stay protected from evil eye, magic or any other kind of evil, we should regularly read morning and evening Adhkaar for protection, stay connected with Quran and keep ourselves and our houses clean and most importantly, we should trust in Allah swt and have firm belief in Him.
