Allah! There is no God 'worthy of worship' 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 encompass anything of His Knowledge except that which He wills. His Kursi` (foot stool) extends over the heavens and the earth, and He feels no fatigue in guarding and preserving them. And He is the Most High, the Greatest.

Notes

Whoever reads this when he lies down to sleep will have a guardian from Allah remain with him and Satan will not be able to come near him until he rises in the morning.
