Chandogya Upanishad 6:2:1
"Ekam evādvitīyam" — "He is One only without a second." (Radhakrishnan, The Principal Upanishads, pp. 447–448)
[112:1] Proclaim, "He is the One and only GOD.
Every scripture that the project has so far examined contains, in its own words and its own language, the declaration that GOD is one, without a second, without parent or equal, and that He is called by many names but is one. The Quran's own touchstone is Sura 112: "Proclaim, 'He is the One and only GOD. The Absolute GOD. Never did He beget. Nor was He begotten. None equals Him.'" The Vedas and Upanishads say ekam evādvitīyam ("one only, without a second") and na tasya pratimā asti ("there is no likeness of Him"); the Torah says Shema Yisrael, Adonai Eloheinu, Adonai Eḥad and Jesus repeats it word for word as the first commandment; Isaiah says "I am God, and there is none else"; the Sikh Mul Mantra says One, True Name, Creator, unborn, self-existent. The name itself travels: Hebrew El/Eloah/Elohim, Aramaic Elah/Alaha (the word on Jesus' lips), Arabic Allah are one Semitic word, and the Quran says of every true name in every tongue, "Call Him GOD, or call Him Most Gracious; whichever name you use, to Him belongs the best names" (17:110). This is the first and the widest strand; the honest caveat, which the sources themselves make, is that the common ground is with the scriptures of each tradition, not always with its popular practice.

"Na casya kascij janita na cadhipah" — "Of Him there are neither parents nor Lord." Full: "Of him there is no master in the world, no ruler, nor is there any mark of him. He is the cause, the lord of the lords of the sense organs; of him there is neither progenitor nor lord." (Radhakrishnan p. 745)

"They have styled (Him, God or the sun) indra (the resplendent), mitra (the surveyor), varuna (the venerable), agni (the adorable)… for learned priests call one by many names as they speak of the adorable as yama (ordainer) and matarisvan (cosmic breath)." Sanskrit ekaṁ sad viprā bahudhā vadanti

The Quran never calls GOD "Father"; Abb is easier than Rabb, yet Rabb abounds.

To a Hindu listener, begin with the apostrophe-s: the common Hindu says "everything is God", the Quran says "everything is GOD's" (Isha 1 ↔ 2:255), and the learned Hindu already knows the Vedas say One without a second. Show Chandogya 6:2:1 and Shvetashvatara 6:8–9 in Radhakrishnan's translation (a Hindu's translation, not a Muslim's), then Rigveda 1:164:46 for the many names, then read Sura 112 and let the listener hear the same four lines. To a Jewish or Christian listener, begin with the Shema as Moses gave it and as Jesus repeated it, then Isaiah 46:9 and 40:18 beside 112:4, then John 17:3 beside 4:171. To a Sikh, read the Mul Mantra beside Sura 112 and Kabir beside 39:8. Do not open with the names-of-GOD etymologies; close with 17:110 — "whichever name you use, to Him belongs the best names" — so that the listener hears that the project is not asking them to change the word they already use for GOD. Never belittle the images or the deity-names the listener grew up with (6:108; R23); the point is that their own scripture already says what the Quran says.
