The Messenger of Allah (Sallallaahu ‘alaihi wasallam) said: “Abu Mundhir! Do you know which Ayah in Allah’s Book is the greatest?”
I replied: “It is `Allah la ilaha illa Huwal-Haiyul-Qayum (Allah! none has the right to be worshipped but He, the Ever Living…)’.” (Al-Quran – 2 : 255).
Thereupon he (Sallallaahu ‘alaihi wasallam) patted me in the chest and said, “Rejoice by this knowledge, O Abu Mundhir!”
The words cited in the Hadith occur at the beginning of Ayat-ul-Kursi (No. 255 of Surat Al-Baqarah of the Qur’an). The merits mentioned in the Hadith are for the whole Ayah. Ayat-ul-Kursi mentions the Majestic Attributes and Mighty Powers of Allah and is, therefore, very meritorious.
“Rejoice by this knowledge” means “May this knowledge be a source of respect, honour and benefit to you.” And knowledge here stands for the knowledge of the Qur’an and Hadith which is certainly a means of success in this world and the Hereafter.
