According to Dr Sharib:-

"Al-'Azim is the One Whose grandeur, greatness and majesty surpass all
human wisdom and understanding. He, in His power. position and status is so
lofty and great that He is independent of the help of others."

"To emulate the name you should cast aside pride and take to humbleness
and meekness."

Appropriate recitation of the name acts as a safety valve, confers honour and
gives recovery from any type of disease.

Some other references:

Al-Ghazali tells us that in human perception things are 'tremendous' in
comparison with what perceives them, or with that to which they are compared.
In other words that for humans it is a relative thing. The tremendousness of
God is not relative to anything.

(Al-Ghazali - The Ninety-nine Beautiful Names of God. Trans. Burrel/Daher: ITS: 1992.)

'Some are born great, some achieve greatness, and some have greatness
thrust upon them.'

William Shakespeare. Twelfth Night.

In the case of humans we refer to greatness as the capacity of an individual to
excel in a specific quality, or skill, or capability - such as when we describe
someone as a great artist, a great sportsman, a great king, a great doctor, a
great lover, a great statesman etc. We use the term great (not always
appropriately), because there is a quality about the performance of that
individual that seems to partake of an altogether higher level than the mere
conjunction of a set of sub skills. Somehow the performance is endowed with a
special quality that lifts it above the normal.

This suggests that the skill, or capacity, or quality, exists at a transcendent
level which is somehow accessible to that individual. Thus we may think that
there is a transcendental level within which these skills exist. Within that level
the skills are merely skills, but when perceived from the level of ordinary
awareness the transcendental quality that imbues them causes us to describe
them as great. Thus genuine greatness in man is in reality a hint of the quality
of greatness that dwells with God and belongs to Him alone.

Some sportsmen or artists have described moments when they became aware,
if only briefly, of functioning at a higher level in which what normally seemed
difficult or impossible suddenly appeared easy and natural. Psychologists call
these 'peak experiences'.

Thus one who we call a 'great doctor', if we are accurate in our assessment,
actually simply has access to the skill of healing as it exists transcendentally -
which is more than enough in this world to merit the term 'great'. Thus we may
say, as I have heard Dr Sharib say, that "rather than saying 'God is great', we
may better say, 'greatness belongs to God'".

The Great One
The Magnificent, The Tremendous, The Supreme
(Al-'Azeem, Al-'Aziim)
Qur'an 2:255
Allah! There is no god
But He, the Living,
The Self-subsisting, Eternal,
No slumber can seize Him Nor sleep.
His are all things
In the heavens and on earth.
Who is there can intercede
In His presence except
As He permitteth? He knoweth
What (appeareth to His creatures
As) Before or After
Or Behind them
Nor shall they compass aught of His
Except as He willeth.
His throne doth extend
Over the heavens
And the earth, and He feeleth
No fatigue in guarding
And preserving them
For He is the Most High
The Supreme (in glory).
