The reality of the jinn, whether they have an effect on humans, and how to protect oneself from them?

Question:
May Allah reward you. Among the questions that came in, it says: Honorable Shaykh Salih, we love you for the sake of Allah, and our question is: We debated with some colleagues regarding an important issue, and I want the Shaykh to answer it. It is about the jinn and their reality, and whether the jinn have an effect on humans? And what is the method of protection from them?

Answer:
The jinn are another realm alongside the realm of humans. Allah (Exalted and Majestic is He) addressed the jinn and the humans, saying, "O assembly of jinn and humans." The jinn are obligated, just as humans are obligated, to worship Allah and obey Him. Among them are the believer, the disbeliever, the upright, the sinner, and the wrongdoer. They are exactly like humans. They are a realm other than the realm of the unseen; we do not see them, though some people may see them or see something of them or one of them, but this is not a permanent state. The norm is that they are from the realm of the unseen. We believe in them even if we do not see them. Yes, they do exert power over humans if they do not protect themselves by obeying Allah (Mighty and Majestic) and remembering Him. If they do not, their Shayatins (devils) harm the children of Adam, and nothing saves them from this except the remembrance of Allah (Glorified and Exalted is He). Likewise, they may strike a person and afflict him with possession, as He (Exalted and Majestic is He) said: The Shaytan flows through the son of Adam like blood, as mentioned in the hadith. So he has the ability that Allah gave him for that. But if the Muslim protects himself with the remembrance of Allah, it will not harm him. Therefore, if humans are afflicted with possession by the jinn, one recites for them from the Qur'an and from the lawful supplications, and then the jinn leave because they cannot bear the remembrance of Allah, for the Shaytan cannot bear the remembrance of Allah. So he leaves and exits in humiliation and disgrace, and Allah protects the Muslim from him. Yes.
