Ayatul Kursi means “Verse of the Footstool”. It is the 255th ayah (verse) of Surah Al-Baqarah and it is the greatest ayah in the Quran.
This is the ayah:
“Allah! Laa ilaaha 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 Kursi 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.” [Surah Al-Baqarah (2) :255]
