All perfect praise be to Allah the Lord of The Worlds. May His peace and blessings be upon our Prophet Mohammad and upon all his family and companions.
Scholars have two opinions in this regard:
First: This is permissible because adoration under dictionary definition is "Admiring the beloved or showing exaggerated love." If "I adore Allah" is used to show one`s strong love to Allah the Almighty along with clearing Him the Exalted from any negative connotations that don`t befit His Majesty, then this is permissible.
Accordingly, this is the meaning intended by scholars when they use this expression in their books. For more details, check the book [`Ehya` Ulum Al-Deen, v.2 pp.280] by Imam al-Ghazali (May Allah have mercy on him).
Second: It isn`t permissible to use the term "adore" to describe love for Allah since adoration is exaggerated love that corrupts one`s nature……." For more details, kindly check the book entitled [Fatawa Al-Iz Ibn Abdellsalam, No. 192.]. And Allah The Almighty Knows Best.
