1.وَإِمَّا يَنزَغَنَّكَ مِنَ ٱلشَّيۡطَـٰنِ نَزۡغٌ۬ فَٱسۡتَعِذۡ بِٱللَّهِۖ إِنَّهُ ۥ هُوَ ٱلسَّمِيعُ ٱلۡعَلِيمُ “And if there comes to you from Satan an evil suggestion, then seek refuge in Allah. Indeed, He is the Hearing, the Knowing.” [41:36]
2. Recitation of the two soorahs al-Falaq,
قُلۡ أَعُوذُ بِرَبِّ ٱلۡفَلَقِ (١) مِن شَرِّ مَا خَلَقَ (٢) وَمِن شَرِّ غَاسِقٍ إِذَا وَقَبَ (٣) وَمِن شَرِّ ٱلنَّفَّـٰثَـٰتِ فِى ٱلۡعُقَدِ (٤) وَمِن شَرِّ حَاسِدٍ إِذَا حَسَدَ (٥
Say: "I seek refuge with (Allâh) the Lord of the daybreak, (1) "From the evil of what He has created; (2) "And from the evil of the darkening (night) as it comes with its darkness; (or the moon as it sets or goes away) (3) "And from the evil of those who practise witchcrafts when they blow in the knots, (4) "And from the evil of the envier when he envies." (5)
قُلۡ أَعُوذُ بِرَبِّ ٱلنَّاسِ (١) مَلِكِ ٱلنَّاسِ (٢) إِلَـٰهِ ٱلنَّاسِ (٣) مِن شَرِّ ٱلۡوَسۡوَاسِ ٱلۡخَنَّاسِ (٤) ٱلَّذِى يُوَسۡوِسُ فِى صُدُورِ ٱلنَّاسِ (٥) مِنَ ٱلۡجِنَّةِ وَٱلنَّاسِ (٦
Say: "I seek refuge with (Allâh) the Lord of mankind, (1) "The King of mankind —  (2) "The Ilâh (God) of mankind, (3) "From the evil of the whisperer (devil who whispers evil in the hearts of men) who withdraws (from his whispering in one's heart after one remembers Allâh) , (4) "Who whispers in the breasts of mankind, (5) "Of jinn and men." (6)
as they have wondrous effect in seeking refuge with Allah from his evil, weakening Shaytan and protection from him. This is why the Messenger, sallallahu `alayhi wa sallam, said: “No person seeks refuge with anything like the Mu`awwidhatayn (soorahs al-Falaq and an-Nas)”. [an-Nasaa’i, 5337]3. Recitation of Ayat al-Kursi (2:255).
ٱللَّهُ لَآ إِلَـٰهَ إِلَّا هُوَ ٱلۡحَىُّ ٱلۡقَيُّومُۚ لَا تَأۡخُذُهُ ۥ سِنَةٌ۬ وَلَا نَوۡمٌ۬ۚ لَّهُ ۥ مَا فِى ٱلسَّمَـٰوَٲتِ وَمَا فِى ٱلۡأَرۡضِۗ مَن ذَا ٱلَّذِى يَشۡفَعُ عِندَهُ ۥۤ إِلَّا بِإِذۡنِهِۦۚ يَعۡلَمُ مَا بَيۡنَ أَيۡدِيهِمۡ وَمَا خَلۡفَهُمۡۖ وَلَا يُحِيطُونَ بِشَىۡءٍ۬ مِّنۡ عِلۡمِهِۦۤ إِلَّا بِمَا شَآءَۚ وَسِعَ كُرۡسِيُّهُ ٱلسَّمَـٰوَٲتِ وَٱلۡأَرۡضَۖ وَلَا يَـُٔودُهُ ۥ حِفۡظُهُمَاۚ وَهُوَ ٱلۡعَلِىُّ ٱلۡعَظِيمُ (٢٥٥
Allâh! Lâ ilâha illa Huwa (none has the right to be worshipped but He), the Ever Living, the One Who sustains and protects all that exists. Neither slumber, nor sleep overtake Him. To Him belongs whatever is in the heavens and whatever is on earth. Who is he that can intercede with Him except with His Permission? He knows what happens to them (His creatures) in this world, and what will happen to them in the Hereafter . And they will never compass anything of His Knowledge except that which He wills. His Kursî extends over the heavens and the earth, and He feels no fatigue in guarding and preserving them. And He is the Most High, the Most Great.
4. Recitation of soorah al-Baqarah. The Messenger, sallallahu `alayhi wa sallam, said, “The house in which al-Baqarah is recited is not approached by Shaytan.” [Muslim]
5. The final part of al-Baqarah. The Messenger, sallallahu `alayhi wa sallam, said, “Whoever recites the two last verses of al-Baqarah at night they will suffice him.” [Muslim]
6. Recitation of the beginning of soorah Mu’min (Ghafir), until His saying, “wa ilayhi-l-maseer” (to Him is the destination). (i.e.حمٓ (١) تَنزِيلُ ٱلۡكِتَـٰبِ مِنَ ٱللَّهِ ٱلۡعَزِيزِ ٱلۡعَلِيمِ (٢ “Ha. Meem. The revelation of the Book is from Allah, the Exalted in Might, the Knowing, the forgiver of sin, acceptor of repentance, severe in punishment, owner of abundance. There is no deity except Him; to Him is the destination.” [40:1-2])
7. Saying “la ilaha ill Allah wahdahu la sharika lah, lahul mulku wa lahul hamdu wa huwa `ala kulli shay’in qadir” (there is nothing worthy of worship except Allah, He has no partner, His is the Dominion and Praise, and He is able to do all things) a hundred times.
8. The most beneficial form of protection from Shaytan: abundance of remembrance of Allah, the Exalted.
9. Ablution and prayer, and they are from among the greatest means of protection, especially at the time of emergence of anger and desire.
10. Abstinence from excess speech, food and mixing with people.
