Tafseer Ahsan Ul Bayan English Pdf [better] -

This verse establishes the core principle of Tawhid – worship is due to Allah alone. The repetition of “You Alone” negates any form of polytheism. Asking for help exclusively from Allah differentiates a believer from those who seek aid from the dead, saints, or idols. The verse implies that true reliance (tawakkul) is only upon Allah in all matters, religious and worldly.
