That is because Allah 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 Batil (falsehood) And verily, Allah He is the Most High, the Most Great.
Hayo ni kwa kuwa Mwenyezi Mungu ndiye Wa Kweli, na kwamba wale wanao waomba badala yake, ni baat'ili, na hakika Mwenyezi Mungu ndiye Aliye Juu na ndiye Mkubwa.
