Ayatul Kursi - Surah Al Baqarah 2:255

أَعُوْذُ بِاللّٰهِ مِنَ الشَّيْطَانِ الرَّجِيْمِ

I take refuge with Allaah from the accursed devil.

A 'oothu billaahi minash-Shaytaanir-rajeem.

Then recite Aayatul-Kursee:

اَللّٰهُ لَاۤ اِلٰهَ اِلَّا هُوَ الۡحَـىُّ الۡقَيُّوۡمُ

Allah! There is none worthy of worship but He, the Ever Living, the One Who sustains and protects all that exists.

Allaahu laa 'ilaaha 'illaa Huwal-Hayyul-Qayyoom,

لَا تَاۡخُذُهٗ سِنَةٌ وَّلَا نَوۡمٌ

Neither slumber nor sleep overtakes Him.

laa ta'khuthuhu sinatun wa laa nawm,

لَهٗ مَا فِى السَّمٰوٰتِ وَمَا فِى الۡاَرۡضِ

To Him belongs whatever is in the heavens and whatever is on the earth.

lahu maa fis-samaawaati wa maafil-'ardh,

مَنۡ ذَا الَّذِىۡ يَشۡفَعُ عِنۡدَهٗۤ اِلَّا بِاِذۡنِهٖ

Who is he that can intercede with Him except with His Permission?

man thal-lathee yashfa'u 'indahu 'illaa bi'ithnih,

يَعۡلَمُ مَا بَيۡنَ اَيۡدِيۡهِمۡ وَمَا خَلۡفَهُمۡ

He knows what happens to them in this world, and what will happen to them in the Hereafter.

ya'lamu maa bayna 'aydeehim wa maa khalfahum,

وَلَا يُحِيۡطُوۡنَ بِشَىۡءٍ مِّنۡ عِلۡمِهٖۤ اِلَّا بِمَا شَآءَ

And they will never compass anything of His Knowledge except that which He wills.

wa laa yuheetoona bishay'im-min 'ilmihi 'illaa bimaa shaa'a,

وَسِعَ كُرۡسِيُّهُ السَّمٰوٰتِ وَالۡاَرۡضَ

His Throne extends over the heavens and the earth,

wasi'a kursiyyuhus-samaawaati wal'ardh,

وَلَا يَـــُٔوۡدُهٗ حِفۡظُهُمَا

and He feels no fatigue in guarding and preserving them.

wa laa ya'ooduhu hifdhuhumaa,

وَهُوَ الۡعَلِىُّ الۡعَظِيۡمُ

And He is the Most High, the Most Great.

wa Huwal-'Aliyyul- 'Adheem.

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 he retires in the evening will be protected from them until he rises in the morning.
