Translation of Ayatul-Kursi:
Allah - There is no god but He, the Ever-living,
the Self-subsisting by Whom all subsist. Slumber overtakes Him not nor sleep.
To Him belongs whatever is in the heavens and whatever is in the earth.
Who is he who can intercede with Him but by His permission?
He knows what is before them and what is behind them.
And they encompass nothing of His knowledge except what He pleases.
His knowledge extends over the heavens and the earth,
and the preservation of them both tires Him not.
And He is the Most High, the Great. (Al-Qur'an 2:255)
***Ayatul Kursi is also known as the Verse of Knowledge, because
it deals with the all-comprehensive knowledge of Allah. Many
Muslims believe that wearing this verse helps protect one from evil
(with Allah's permission) because of its greatness and blessings.
