Ayatul Kursi (One time)-

اللَّـهُ لَا إِلَـٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ ۚ لَا تَأْخُذُهُ سِنَةٌ وَلَا نَوْمٌ ۚ لَّهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ ۗ مَنْ ذَا الَّذِي يَشْفَعُ عِنْدَهُ إِلَّا بِإِذْنِهِ ۚ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ ۖ وَلَا يُحِيطُونَ بِشَيْءٍ مِّنْ عِلْمِهِ إِلَّا بِمَا شَاءَ ۚ وَسِعَ كُرْسِيُّهُ السَّمَاوَاتِ وَالْأَرْضَ ۖ وَلَا يَئُودُهُ حِفْظُهُمَا ۚ وَهُوَ الْعَلِيُّ الْعَظِيمُ ﴿٢٥٥﴾

Allahu laa 'ilaaha 'illaa Huwal-Haiyul-Qayyoom, laa ta'khuthuhu sinatun walaa nawm, lahu maa fis-samaawaati wamaa fil-'ardhi, man thal-lathee yashfa'u 'indahu 'illaa bi'ithnihi, ya'lamu maa bayna 'aydeehim wa maa khalfahum, wa laa yuheetoona bishay'im-min 'ilmihi 'illaa bimaa shaa'a, wasi'a kursiyyuhus-samaawaati wal'ardh, wa laa ya'ooduhu hifdhuhumaa, wa Huwal-'Aliyyul- 'Adheem.

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 compass 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. Ubay bin Ka’ab (RA) reported that, anyone recite ayatul kursi in the morning he will be protected from Jinn till the evening and if he recite in the evening he will be protected from Jinn till the morning. Note: If anyone recite it after Fajr prayer one time then he will get both the benefits of reciting it in the morning and benefits of reciting it after Fajr prayer.
