For those who are not familiar with it (although I think 99.99% of all Muslims are familiar), the Ayat al Kursi is called the Throne verse. It's a very powerful verse that many many Muslims recite every day. Here is a
bit on why it's so revered:
The reason why Ayat al-Kursi is the most excellent verse, is that this verse mentions the names of Allah Most High more than any other verse (i.e. this verse contains the most remembrance (dhikr) of Allah Most High). For example, some verses of the Quran may mention the names of Allah Most High two times, some may mention the names of Allah Most High four times, and some ten times. But in Ayat al-Kursi, the names of Allah Most High have been mentioned seventeen times. Ayat al-Kursi mentions six attributes (sifat) of Allah Most High, all six being mentioned in this single verse. The attributes mentioned are: the Divine Oneness (Wahdaniyyah) of Allah Most High, His/Her Life (Hayah), His/Her Knowledge (‘Ilm), His/Her Kingdom (Mulk), His/Her Divine Power (Qudrah) and His/Her Will (Iradah).
In the name of God/Goddess, Most Merciful, Most Compassionate
Allah! There is no Goddess but She,
The Ever-Living, the Self-Subsistent, Eternal.
No slumber can seize Her nor sleep.
Hers are all things in the heavens and on Earth.
Who is there that can intercede with Her unless it be by Her leave?
She knows all that lies open before women and men, and all that is hidden from them, whereas they cannot attain to aught of Her knowledge except as She wills it.
Her eternal power overspreads the heavens and the earth,
and their upholding wearies Her not.
And She alone is Truly Exalted, Tremendous.
