The glorious Qur'an is the strong rope of Allah and His straight path. Its recitation brings goodness and blessing and affords tranquility of the soul and abundance of reward. Allah endowed some of its Surahs and verses with a special merit. In this Hadīth, ’Ubayy ibn Ka‘b (may Allah be pleased with him) relates that the Messenger of Allah (may Allah's peace and blessings be upon him) one day asked him: "O Abu al-Mundhir", a surname for ’Ubayy ibn Ka‘b (may Allah be pleased with him). "Do you know which verse of Allah's Book that you have is the greatest?" i.e., in terms of the reward and benefit for its reciter in this world and the Hereafter. ’Ubayy (may Allah be pleased with him) said: "I said: Allah and His Messenger know best." This stems from the Companions' politeness towards the Prophet (may Allah's peace and blessings be upon him). It was said: ’Ubayy knew which verse was the greatest when the Messenger of Allah (may Allah's peace and blessings be upon him) asked him about it, but he did not reply out of respect, modesty, and politeness towards him (may Allah's peace and blessings be upon him). If he had answered him the first time he asked him, he would have thus displayed his knowledge. He also probably did not give the answer because he expected that the Messenger of Allah (may Allah's peace and blessings be upon him) would probably tell him that another verse is greater than that or inform him of some other benefit. When the Prophet (may Allah's peace and blessings be upon him) repeated the question, he knew that the Prophet (may Allah's peace and blessings be upon him) wanted him to answer and wanted to test his memorization and information. Thereupon, he answered him that the greatest verse - as far as he knew - is the one that reads: {Allah: none has the right to be worshiped except Him, the Ever-Living, All-Sustaining. Neither drowsiness overtakes Him nor sleep. To Him belongs all that is in the heavens and all that is on earth. Who is there that can intercede with Him except with His permission? He knows what was before them and what will be after them, while they encompass nothing of His knowledge, except what He wills. His Kursī [footstool] extends over the heavens and earth, and safeguarding of both does not weary Him, for He is the Most High, the Most Great.} [Surat al-Baqarah: 255] It is called the verse of Kursī. So, the Prophet (may Allah's peace and blessings be upon him) approved his answer and accepted it as correct, and he struck with his honorable hand on the chest of ’Ubayy (may Allah be pleased with him). This behavior on the Prophet's part was done by way of gentleness, given his approval and acceptance of this answer and his admiration of the answerer. He said to him: "May knowledge be pleasant for you, O Abu al-Mundhir," i.e., may knowledge be blissful for you. This is meant as a supplication for him to find knowledge easily and be versed therein. The verse of Kursī is the greatest verse in the Qur'an because it combines such fundamental divine names and attributes that are not combined in any other verse. In it, Allah Almighty describes Himself as the worshiped God other than Whom none is truly worthy of worship. He alone is worthy of worship, out of love and exaltation for Him, given the perfection of His attributes. To Him belongs the complete life, which was not preceded by non-existence, will not be followed by an end, and entails all attributes of perfection. He is Self-Sustaining and does not need anyone, and He undertakes the affairs of His creation, including sustenance and other things. All creatures stand in need of Him and cannot exist without Him. His support of their existence entails all actions of perfection. Part of the perfection of His life and sustainability is that He does not suffer drowsiness or get overcome by sleep, and He is the sole Possessor of all that is in the universe. No one dares to intercede with Him unless He gives him permission. He is the One Who knows all the affairs of His creation; past, present, and future, and all else do not possess anything of Allah's knowledge whatsoever except what He taught them, by His will. His Kursī - the place of His feet - encompassed the heavens and the earth, despite their vastness and greatness, and their preservation is not heavy or hard for Him; rather, this is something easy and simple for Him, Exalted be He. He is the Possessor of absolute exaltedness above all His creation. He is Exalted by His Essence above His Throne and High above His creation by His absolute power and perfect attributes. He is the Possessor of absolute greatness in His Essence, attributes, and authority, and all other than Him are humble before Him and so little next to Him. Nothing is greater than Him, Exalted, Glorified, and Blessed be He. In the Hadīth: A great merit for ’Ubayy ibn Ka‘b (may Allah be pleased with him). And in it: Praising a person to his face, if it serves a good purpose and if self-admiration is not feared, and so on And in it: The knowledgeable person's great respect for his virtuous companions.
