Explaining 'La ilaha illa Allah' with Al-Hakimiyyah
The explanation of
Muhammad Qutb to Al-Hakimiyyah in the book that you referred to is incorrect. The correct explanation of the great word
"La ilaha illa Allah" is that there is no true deity worthy of worship except Allah (Glorified and Exalted be He). Allah (Exalted be He) says: (Part No. 2; Page No. 40)
That is because Allâh - He is the Truth (the only True God of all that exists, Who has no partners or rivals with Him), and what they (the polytheists) invoke besides Him, it is Bâtil (falsehood). And verily, Allâh - He is the Most High, the Most Great.
This explanation was given by former and recent scholars. As for Al-Hakimiyyah, it represents one aspect of what "La ilaha illa Allah" means. May Allah increase your knowledge and insight.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
