Many stories about Haroot and Maroot are still there, but they are all false.

Allah blessed Prophet Sulaiman (peace be upon him) with extraordinary miracles mentioned in Surah Sad and Surah Saba. Prophet Sulaiman (peace be upon him) was taught the language of birds by Allah. He ruled the winds. He used to travel on the throne and the mountains used to praise Allah with him. The giants were subservient to him who dived into the seas. It is mentioned in the Holy Qur'an that Prophet Sulaiman (peace be upon him) prayed: "Allah, do not give to anyone what you have given me."

By Allah's command, Prophet Sulaiman (peace be upon him) controlled the devils and jinn.

Regarding this, the only mention in the Holy Quran is that Prophet Sulaiman (peace be upon him) used to work with devils and jinn. The devils stole some knowledge from the angels and stole some of Sulaiman's knowledge and wrote it down in books. Prophet Sulaiman took all those books from them and buried them under his chair in his palace.

When Prophet Sulaiman (peace be upon him) left the world, people found those books after digging under his chair. The followers of Prophet Sulaiman (peace be upon him) started calling him a magician, saying that he was a magician who had books of magic. It is mentioned in the Holy Qur'an that Prophet Sulaiman never disbelieved, but the devils disbelieved. Sulaiman was the Messenger of Allah.

Allah sent Haroot and Maroot to test the companions of Prophet Sulaiman (peace be upon him) in this world to check whether they were sincere with him. These two were the angels of Allah and Allah had taught them a knowledge that separated husband and wife. This knowledge was only given by Allah to test the people of Prophet Sulaiman (peace be upon him). These two angels Haroot and Maroot came to the world in human form by the order of Allah and they used to say to people that we have this knowledge that husband and wife can separate but it is disbelief and you do not learn this from us, because Allah has sent us to test you. But despite all this, the Jews learned satanic knowledge from Haroot and Maroot.

Conclusion

Children of Israel had left the Book of Allah and started learning Satanic practices and magic. Then Allah sent two angels Haroot and Maroot inside the city of Babylon to test these people. There was no fault of Haroot and Maroot, they came by the order of Allah and came to test the people and they used to tell the people that this is a satanic knowledge of disbelief. Therefore, if these people had believed in Allah and developed a path of piety, then they would have their reward from Allah.
