Readings in Tawheed
“No one on earth or in heaven is worshipped with due right except for You, O Allaah.” The phrase “with due right” must be mentioned when explaining the meaning of “Laa Ilaaha illaaAllaah. You must include “due right” or “rightfully” or else the meaning will be wrong. If you were to say: “There is no one worshipped in the heavens or on the earth except for You” we would be contradicting reality since those who are worshipped are many. But the one who is worshipped after all others have been negated is the One who is worshipped in truth or with “due right.”
Every time something is worshipped, it becomes known as a “god” according to the language. It is not called Allaah, but rather a “false” god. The term “god” is general and encompasses the One who is worshipped with due right as well as those that are worshipped wrongfully. The word “Allaah” is specifically reserved for the One who is worshipped with due right – the Creator of the heavens and the earth. Them is no one worshipped in the heavens or the earth (with due right) except for you, O Allaah.
