Question - How do you protect youself from the harm of the Jinn?

Answer

The Sunnah mentions adhkhaar (dhikr) by means of which one may gain protection from the shayaateen (devils). These include: 

Seeking refuge with Allaah from the jinn: 

Allaah says (interpretation of the meaning): 

“And if an evil whisper from Shaytaan (Satan) tries to turn you away (O Muhammad) (from doing good), then seek refuge in Allaah. Verily, He is the All Hearer, the All Knower”[Fussilat 41:36]

“And if an evil whisper comes to you from Shaytaan (Satan), then seek refuge with Allaah. Verily, He is All-Hearer, All-Knower”

[al-A’raaf 7:200] 

It was narrated from Sulaymaan ibn Sard that two men were trading insults in the presence of the Prophet (peace and blessings of Allaah be upon them), until the face of one of them turned red. The Prophet (peace and blessings of Allaah be upon him) said, “I know a word which, if he were to say it, what he is suffering from would go away: ‘A’oodhu Billaahi min al-Shaytaan il-rajeem (I seek refuge with Allaah from the accursed Shaytaan).’”

(Narrated by al-Bukhaari, 3108; Muslim, 2610) 

2 – Reciting al-Mi’wadhatayn (the last two Soorahs of the Qur’aan, al-Falaq and al-Naas). 

It was narrated that Abu Sa’eed al-Khudri (may Allaah be pleased with him) said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) used to seek refuge with Allaah from the jinn and from the evil eye until the Mi’wadhatayn were revealed, and when they were revealed he started to recite them and not anything else.”

(Narrated by al-Tirmidhi, 2058; he said it is hasan ghareeb. Also narrated by al-Nasaa’i, 5494; Ibn Maajah, 3511. The hadeeth was classed as saheeh by al-Albaani (may Allaah have mercy on him) in Saheeh al-Jaami’, 4905). 

3 – Reciting Aayat al-Kursi

It was narrated that Abu Hurayrah said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) put me in charge of guarding the zakaah of Ramadaan. Someone came to me and started grabbing handfuls of the food. I took hold of him and said, ‘I will take you to the Messenger of Allaah (peace and blessings of Allaah be upon him).’ He said, ‘I will teach you some words by means of which Allaah will benefit you.’ I said, ‘What are they?’ He said, ‘When you go to your bed, recite this aayah (interpretation of the meaning): “Allaah! Laa ilaaha illa Huwa (none has the right to be worshipped but He), Al-Hayyul-Qayyoom (the Ever Living, the One Who sustains and protects all that exists)…” [al-Baqarah 2:255] – until he completed the aayah. Then Allaah will appoint a guard for you who will stay with you and no shaytaan (devil) will come near you until morning.’ The Messenger of Allaah (peace and blessings of Allaah be upon him) asked me, ‘What did your prisoner do last night?’ I said, ‘O Messenger of Allaah, he taught me something, and claimed that Allaah would benefit me by it.’ He said, ‘What was it?’ I said, ‘He taught me to recite Aayat al-Kursiy when I go to bed, and said that no shaytaan would come near me until morning, and that Allaah would appoint a guard for me who would stay with me.’ The Prophet (peace and blessings of Allaah be upon him) said, ‘He told you the truth, although he is an inveterate liar. That was the Shaytaan.’”

(Narrated by al-Bukhaari, 3101)

4 – Reciting Soorat al-Baqarah

It was narrated from Abu Hurayrah that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Do not make your houses like graves, for the Shaytaan runs away from a house in which Soorat al-Baqarah is recited.”(Narrated by Muslim, 780)

5 – The last verses of Soorat al-Baqarah

It was narrated that Abu Mas’ood al-Ansaari said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘Whoever recites the last two verses of Soorat al-Baqarah at night, that will suffice him.’” (Narrated by al-Bukhaari, 4723; Muslim, 807)

It was narrated from al-Nu’maan ibn Basheer (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “Allaah inscribed a book two thousand years before He created the heavens and the earth, from which the last two aayahs of Soorat al-Baqarah were revealed. If they are recited for three nights, no shaytaan (devil)will remain in the house).

(Narrated by al-Tirmidhi, 2882. This hadeeth was classed as saheeh by al-Albaani in Saheeh al-Jaami’, 1799).

6 – Reciting “Laa ilaaha ill-Allaah wahdahu laa shareeka lah, lahu’l-mulk wa lahu’l-hamd wa huwa ‘ala kulli shay’in qadeer (There is no god except Allaah Alone with no partner or associate; His is the Sovereignty and His is the praise, and He is Able to do all things)” one hundred times. 

It was narrated from Abu Hurayrah that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Whoever says “Laa ilaaha ill-Allaah wahdahu laa shareeka lah, lahu’l-mulk wa lahu’l-hamd wa huwa ‘ala kulli shay’in qadeer” one hundred times in the day, will have a reward equivalent to that of freeing ten slaves, one hundred hasanahs (good deeds) will be recorded for him, and one hundred sayi’ahs (bad deeds) will be erased from his record, and it will be protection for him from the Shaytaan for that day, until evening comes. No one could achieve any better than him except the one who does more than he did.”

(narrated by al-Bukhaari, 31119; Muslim, 2691) 

7 – Remembering Allaah often (dhikr) 

It was narrated from al-Haarith al-Ash’ari that the Prophet (peace and blessings of Allaah be upon him) said: “Allaah commanded Yahyaa ibn Zakariyah (peace be upon him) five things to follow and to enjoin upon the Children of Israel… and he commanded them to remember Allaah, and the likeness of that is a man who was being pursued by the enemy, until he reached a strong fortress in which he found protection; similarly a man cannot find protection from the Shaytaan except by remembering Allaah…”

(Narrated by al-Tirmidhi, 2863; he said it is hasan saheeh. The hadeeth was classed as saheeh by al-Albaani in Saheeh al-Jaami’, 1724) 

8 – The adhaan 

It was narrated that Suhayl ibn Abi Saalih said: “My father sent me to Bani Haarithah, and there was with me a slave of ours, or a companion of ours. Someone called out his name from a garden, and the one who was with me looked into the garden and did not see anything. I mentioned that to my father, and he said, ‘If I had known that this was going to happen to you, I would not have sent you. But if you hear a voice then make the call for prayer, for I heard Abu Hurayrah (may Allaah be pleased with him) narrating that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “When the Shaytaan hears the call to prayer, he runs away fast.”’”(Narrated by Muslim, 389). 

The word translated here as “runs away fast” may also mean “farting.” 

9 – Reciting Qur’aan offers protection against the Shaytaan 

Allaah says (interpretation of the meaning): 

“And when you (Muhammad) recite the Qur’aan, We put between you and those who believe not in the Hereafter, an invisible veil (or screen their hearts, so they hear or understand it not)[al-Israa’ 17:45]
