Because jinn can see us while we cannot see them, the Prophet (sall Allahu alayhi wasallam) taught us many ways to protect ourselves from their harm. By seeking refuge of Allah from the accursed shaytan, reciting surat al-Falaq and surah An-Naas, Ayat al Kursi and reciting the words taught by Allah in the Qur’an. Allah Almighty says, “And say: My Lord! I seek refuge in Thee from suggestions of the evil ones. And I seek refuge in Thee, my Lord, lest they be present with me.” (Al-Mu’minun: 97-98)
Saying Bismillah (in the Name of Allah) before entering one’s home, eating or drinking and having intercourse will keep shayateen from entering the house or partaking with a person in his food, drink and sexual activity. Similarly, mentioning the name of Allah before entering the toilet or taking off one’s clothes will prevent the jinn from seeing a person in a state of undress or harming him/her. The Prophet (sall Allahu alayhi wasallam) said: “To put a barrier that will prevent the jinn from seeing the `awrah (part of the body which must be covered) of the sons of Adam, let any one of you say ‘Bismillah’ when entering the toilet.” (Reported by At-Tirmidhi)
Showing the world of reality! by Shiekh Answar Al Awlaki. May Allah save us from Sihr! Ameen.
Ibn Hazm said:
“The jinn are real, and they are creatures created by Allaah. Among them are kaafirs and believers. They can see us but we cannot see them. They eat, have children and die. Allaah says (interpretation of the meanings):
“O you assembly of jinn and Mankind!” [al-An’aam 6:130]
“And the jinn, We created aforetime from the smokeless flame of fire” [al-Hijr 15:27]
Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said:
“Undoubtedly the jinn can have a harmful effect on humans, and they could even kill them. They may harm a person by throwing stones at him, or by trying to terrify him, and other things that are proven in the Sunnah or indicated by real events. It was reported that the Messenger (peace and blessings of Allaah be upon him) gave permission to one of his Companions to go to his wife during one of the military campaigns — I think it was the campaign of al-Khandaq — as he was a young man who had recently got married. When he reached his house, he found his wife standing at the door, and he objected to that. She said to him, ‘Go inside,’ so he went inside and found a snake curled up on the bed. He had a spear with him, so he stabbed it with the spear until it died, and at the same instant as the snake died the man also died. It was not known which of them died first, the snake or the man. When the Prophet (peace and blessings of Allaah be upon him) heard of that, he forbade killing the harmless kinds of snakes that are found in houses, apart from those which are maimed or are streaked and malignant.
