                                           OM/AUM DOES NOT EXIST
In their devotion Hindus chant/utter the word Om/Aum (which Hindus consider to refer to God). But Om/Aum is NOT mentioned in the Rg Veda.
Regarding the Gayatri mantra of the RgVeda which reads:

“Tat Savitur Varenyam Bhargo
Devasya Dhi Mahi
Dhiyo Yo Nah Prachodyat”
(“That Sun, bright and pure,
 the god’s great wisdom
–may he sharpen and refine our intellect”)

Abdul Haque Vidyarthi points out in his book Muhammad in World Scriptures that to give meaning to this Gayatri mantra, “the pandits prefix these four words which DOES NOT EXIST in the Veda Om bhur bhava svaha. The word Om, it may be noted, is NOT FOUND ANYWHERE in the Rig Veda. These four words they interpolate and insert before the Gayatri mantra for the reason that it may yield some significance at least.” (Emphasis added, .For more on this see Mohammad-and Moulood).

Another source points out: “Om is not mentioned in the ancient Rig-Veda. The only possible indirect reference is in hymns 1.164.39 which speaks of the syllable (akshara) that exists.”— Presentation transcript” (For more see https://slideplayer.com/slide/7634863/.

Clearly, Om/Aum is meaningless.
OM/AUM DOES NOT EXIST.
