(أعوذ بالله من الشيطان الرجيم)
﴿اللّهُ لاَ إِلَـهَ إِلاَّ هُوَ الْحَيُّ الْقَيُّومُ
لاَ تَأْخُذُهُ سِنَةٌ وَلاَ نَوْمٌ
لَّهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الأَرْضِ
مَن ذَا الَّذِي يَشْفَعُ عِنْدَهُ إِلاَّ بِإِذْنِهِ
يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ
وَلاَ يُحِيطُونَ بِشَيْءٍ مِّنْ عِلْمِهِ إِلاَّ بِمَا شَاء
وَسِعَ كُرْسِيُّهُ السَّمَاوَاتِ وَالأَرْضَ
وَلاَ يَؤُودُهُ حِفْظُهُمَا
وَهُوَ الْعَلِيُّ الْعَظِيمُ﴾
(A`ūdhu billāhi min ash-shaytāni 'r-rajīm)
Allāhu lā ilāha illā huwa ‘l-Ḥayyul-Qayyūm, 
lā ta'khudhuhu sinatun wa lā nawm, 
lahu mā fis-samāwāti wa māfil-arḍ, 
man dhal-ladhī yashfa`u `indahu illā bi'idhnih, 
ya`lamu mā bayna aydīhim wa mā khalfahum, 
wa lā yuḥīṭūna bishay'im-min `ilmihi illā bimā shā', 
wasi`a kursiyyuhus-samāwāti wal-arḍ, 
wa lā ya'ūduhu hifẓuhumā, 
wa huwal-`Aliyyu‘l-`Aẓīm.

(Ayat al-Kursi; Al-Qur'an 2:255)

Allah! There is none worthy of worship but He, the Ever-Living, the One Who sustains and protects all that exists. 
Neither slumber nor sleep overtakes Him. 
To Him belongs whatever is in the heavens and whatever is on the earth. 
Who is he that can intercede with Him except with His Permission? 
He knows what happens to them in this world, and what will happen to them in the Hereafter. 
And they will never encompass anything of His Knowledge except that which He wills.
His Throne 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.

Reference:
Whoever says this when he rises in the morning will be protected from jinns until he retires in the evening, and whoever says it when retiring in the evening will be protected from them until he rises in the morning. It was 
reported by Al-Hakim 1 / 562, Al-Albani graded it as authentic in 
Sahihut-Targhib wat-Tarhib 1/273, and traces it to An-Nasa'i and 
At-Tabarani. He says that At-Tabarani's chain of transmission is reliable 
(Jayyid).
