The word “Al-Jalil” is never mentioned in the Qur’an. However, the Qur’an uses the word “Dhul Jalal.” Al-Jalil literally means “big camel”. Then scholars understand it as “the nature of a great body”, or “high position”, or also “an important role”. However, related to the context of the nature of Allah, Al-Jalil means “The Most All”.
Imam Az-Zujaj said that Al-Jalal means “majesty”. Meanwhile, Sheikh Hafidz Hukmi interprets Al-Jalil as “something that is big and everything, cannot be resisted by others.”
Al-Jalil is the Essence who has majesty and glory. This is confirmed in the Qur’an: “And the face of your Lord will endure, which has greatness and glory. So which of the favors of your Lord would you deny?” (Surat Ar-Rahman: 27-28)
The attributes of greatness, according to Imam Al-Ghazali include the Most Rich (No Need), Most Holy, All Knowing, All Powerful, and others. Imam Ar-Razy in his commentary explained that the word Jalal contains a sign of “denying”, such as that Allah is not in physical form, does not need, is not weak, and so on. Thus, based on this understanding, it means that the meanings of Al-Khabiir, Al-Adzim, and Al-Jalil are different.
It is narrated in a narration that the Messenger of Allah (SAW) heard a man praying in the mosque, “O Allah, I ask You that You are the One Who has all praise. There is no god but You. You are the One, You have no partner. The One who created the heavens and the earth, who has majesty and glory.” The Messenger of Allah then explained, “He really has asked Allah by using His great name, which if He is asked with him he will certainly give, and if he is asked with him he will also answer.
