Thanks, Syed Shaib for bringing this Sura. However, the word GOD is used by ALL RELIGIONS as a title; which is very different than the entity mentioned in these verses. All religions of this world use this title GOD to justify an entity for worship and adoration in, their own traditional manners.
However, in this very Sura, which some consider to be a touch stone of Unity. Never, a word is mentioned about worship and adoration. Hence, how come all religions including prevalent Islam is insistent upon having a GOD? That is GOD used as title for either a deity perceived by senses or an unperceived deity, for worship and adoration.
