AL-AHAD-The Unique, The Only One The Sole One

The One who is unique in both His essence and attributes. There is no one or nothing like Him and He was, is and will forever be the unequaled amid indivisible Only One.
Allah, Exalted be He, says, “He is the One, the Supreme and Irresistible.” (Surat Ar-Ra’d, 13:16); “Say, ‘He is Allah, the One and Only.’ ” (Surat AlIkhlaas, 112:1)
He is, and has always been, one, without anyone else with Him. He is unique and there is no one like Him in His being, just as He is unique in His attributes, actions and lordship. He is the only One who deserves to be worshipped.

The One whose deeds are glorious, dignified, noble, honorable and exceedingly generous.

The One whose deeds and ways are noble, great and bountiful.

The One who shows mankind the highest, most perfect example of goodness, richness, and generosity.

From the root m-j-d which has the following classical Arabic connotations:

to be glorious, dignified, noble and honorable
to be lauded, exalted, sublime
to be liberal, bountiful, exceedingly generous

The name Mājid is not specifically used as a Beautiful Name in the Qur’ān.

Al-Majīd indicates the One whose essential nature is glorious, dignified, noble and honorable, and whose essential nature is to give liberally and bountifully.

Al-Mājid denotes the One who is praised for the specific deeds and attributes of great glory, dignity, nobility, honor, and exceeding generosity.

That is, the name al-Majīd denotes the glorious essential nature of the One, while the name al-Mājid honors specific deeds performed by the One.
