What is the validity of the poet’s saying: “Allah is my Lord, I have no god but Him *** Is there any god in existence but Him?”

Question:
He says: Honorable Shaykh, may Allah grant you success, I read a book that speaks about the greatness of Allah (Glorified and Exalted is He), and among the contents of this book is this verse: “Allah is my Lord, I have no god but Him, is there any god in existence but Him?” Does this verse indicate the greatness of Allah? No.

Answer:
The statement “there is no god in existence but Him” is incorrect, for there are many gods in existence, but there is no god worthy of worship except Allah. So if the word “worthy” were added, it would be correct. As for denying the existence of gods absolutely, this necessitates the unity of existence, which is what those who say that all objects of worship are Allah claim; that the one who worships a grave, the one who worships an idol, the one who worships a tree or a stone, has not worshipped anything but Allah, because there is no god but Allah. This is not permissible. One must qualify it by saying “there is no object of worship worthy of worship,” or “there is no god worthy of worship,” or “there is no god in existence worthy of worship except Allah (Exalted and Majestic is He).” By doing so, the gods that are not worthy of worship, which are false, are excluded. Yes.
