What is Ayat al-Kursi and what is its virtue?

The verse

"Allah — there is no deity except Him, the Ever-Living, the Sustainer of existence. Neither drowsiness overtakes Him nor sleep. To Him belongs whatever is in the heavens and whatever is on the earth. Who is it that can intercede with Him except by His permission? He knows what is before them and what will be after them, and they encompass nothing of His knowledge except what He wills. His Kursi extends over the heavens and the earth, and their preservation tires Him not. And He is the Most High, the Most Great."— Qur'an 2:255

Shaykh Ibn Baz explains that the verse ends at "and He is the Most High, the Most Great" — the following verse, "There is no compulsion in religion," is a separate ayah. It is named Ayat al-Kursi (the Verse of the Kursi) because of the mention of the Kursi within it.

Why it is the greatest verse

The Prophet ﷺ asked Ubayy ibn Ka'b which verse of the Book of Allah was greatest. Ubayy answered with this verse, and the Prophet ﷺ struck his chest and said, "May the knowledge delight you, O Abu al-Mundhir." This confirmed both the verse's rank and Ubayy's understanding of it.

Shaykh Ibn Baz and Shaykh Ibn Uthaymeen both note that the verse is called the greatest because it gathers meanings no other single verse gathers: the oneness of Allah, the affirmation of His names and attributes, the vastness of His knowledge, His complete power, and His absolute sovereignty. Ibn Kathir, as reported by IslamWeb (fatwa 62487), counted ten independent statements within it.

What the verse teaches about Allah

The verse opens with the words of tawhid — "Allah, there is no deity except Him" — meaning there is no being truly worthy of worship except Him. Ibn Baz explains that al-Ilah means al-Ma'luh, the One worshipped, so the phrase negates every false object of worship.

The Ever-Living and the Sustainer

Shaykh Ibn Uthaymeen explains that al-Hayy (the Ever-Living) is the One whose life is perfect, never preceded by non-existence and never followed by decay. al-Qayyum (the Sustainer) is the One who stands by Himself, independent of all creation, while all creation depends on Him. Ibn Baz adds that al-Qayyum is the One who establishes His servants, maintains His creation, and preserves all things — nothing stands except by Him.

Al-Sa'di notes that al-Hayy encompasses all attributes of the Essence, and al-Qayyum encompasses all attributes of action. These two names together contain every form of perfection, which is why it is reported that they are the Greatest Name of Allah — the name by which, when He is called upon, He answers.

Neither drowsiness nor sleep

"Neither drowsiness overtakes Him nor sleep" — sinah is light drowsiness, and nawm is deep sleep. Ibn Baz explains that these are traits of created beings who are subject to weakness and fatigue. Allah is free of them entirely: no drowsiness, no sleep, no death, no heedlessness. His life is complete.

His dominion and knowledge

"To Him belongs whatever is in the heavens and whatever is on the earth" — all of creation are His servants and His property, none outside His dominion. "Who is it that can intercede with Him except by His permission?" — no one, not even the Prophet ﷺ, may intercede on the Day of Judgment until Allah grants permission. Al-Sa'di explains that intercession is only granted for those whom Allah is pleased with, and He is only pleased with those who upheld His oneness and followed His messengers.

"He knows what is before them and what will be after them" — His knowledge encompasses all that has passed and all that is to come. "And they encompass nothing of His knowledge except what He wills" — no created being knows anything of Allah's knowledge except what He Himself grants.

The Kursi and His preservation

"His Kursi extends over the heavens and the earth" — Ibn Kathir, as cited by IslamWeb, reports that Ibn Abbas said the Kursi here means His knowledge, while others said it is the place of the Feet. Ibn Kathir concluded that the Kursi is not the Throne, and the Throne is greater than it.

"And their preservation tires Him not" — sustaining the heavens and the earth costs Him no effort. "And He is the Most High, the Most Great" — exalted above all, great in His essence and attributes.

Its virtue in practice

The verse's protection is established in authentic narrations. In the well-known hadith of Abu Hurayrah رضي الله عنه, a jinn who was stealing from the charity dates taught him to recite Ayat al-Kursi at bedtime, saying it would keep a guardian from Allah over him and no devil would come near him until morning. When Abu Hurayrah reported this to the Prophet ﷺ, he said, "He told you the truth, though he is a liar."

Shaykh Ibn Taymiyyah رحمه الله notes that Ayat al-Kursi drives away devils — when it is recited sincerely in situations of satanic influence, it nullifies them.

The scholars also mention reciting it after the five daily prayers. Ibn Baz describes this as a sunnah supported by several hadiths, some weak and some good.

Key takeaways

• Ayat al-Kursi is Qur'an 2:255, the greatest verse in the Book of Allah, confirmed by the Prophet ﷺ in the hadith of Ubayy ibn Ka'b.
• It gathers the core of tawhid: Allah's oneness, His names al-Hayy and al-Qayyum, His perfect freedom from weakness, His absolute dominion, His all-encompassing knowledge, and His effortless preservation of creation.
• Reciting it at night brings protection: a guardian from Allah remains over the reciter and no devil approaches until morning.
• Reciting it after the five daily prayers is a sunnah, supported by narrations of varying strength.
• The Kursi is not the Throne — Ibn Kathir held the Kursi to be distinct and the Throne greater, though some earlier scholars said the Kursi here refers to Allah's knowledge.
