(Al-Kafiroon) 109 : 3
وَلَا أَنْتُمْ عَابِدُونَ مَا أَعْبُدُ
And You are not serving Whom I am serving.
The believer believes with Allah- the Lord of the worlds- Who has no particular relation with any nation, religion, caste, sex, color, language etc. except with the Heedful. Heedful are those who received the Truth-Adhikr- and made It truth is told in the verse: 39: 33. Read together 2: 62 and 49: 13. Believer worships the Believer- Allah- whereas the disbelievers worship the Kafir-Satan. Believer considers Impartial Allah as the Monarch, Dictator, supreme Almighty etc. whereas the disbelievers are having foolish concepts about Him. See the explanation 16: 36; 39: 41 and 103: 1-3.
