Surah Al-Baqarah...
there is no god but He, the Ever-living, the Self-Subsisting (the Sustainer of all things); slumber seizes Him not, nor sleep; to Him belongs whatsoever is in the heavens and whatsoever is in the earth. Who is it that can intercede with Him save by His leave? He knows what is before them and what is behind them, while they comprehend nothing of His knowledge except what He wills.
Once, the Messenger of Allah (S) asked Ubayy-ibn-Ka'b which verse of the verses of the Qur'an was the most important one, and he answered the verse saying: "Allah! there is no god but He, the Ever-living, the Self-subsisting (the Sustainer of all things)..." Then the Messenger of Allah (S) touched his chest as a sign of favour and told him "May your knowledge be wholesome to you.
By the One in Whose hand is Muhammad's soul, this verse has two tongues and two lips which glorify the Lord below the Divine throne of authority," [^3] Another tradition narrated from Imam Baqir (as) says: "The one who recites Ayat-ul-Kursi once, Allah will remove one thousand unbecoming things from his worldly unbecoming affairs, the easiest of which is poverty, and one thousand unbecoming things from his (affairs) in the Hereafter, the easiest one among which is the pain of grave," [^4] The verse begins with the Pure Essence of Allah and continues with the subject of Unity, Asma'-ul-Husna, and His attributes.
It says: "Allah! there is no god but He…" "Allah*"* is the particular appellation for God Which means the Essence that includes all the attributes of Divine Perfection, Glory, and Beauty.
