Tafsir Ibn Kathir -> Surah Az-Zukhruf -> The Idolators admit that Allah Alone is the Creator

﴿وَلَئِن سَأَلْتَهُم مَّنْ خَلَقَهُمْ لَيَقُولُنَّ اللَّهُ فَأَنَّى يُؤْفَكُونَ ﴾

(And if you ask them who created them, they will surely say: "Allah.'' How then are they turned away) means, `if you ask these idolators who associate others in worship with Allah,'

﴿مَّنْ خَلَقَهُمْ لَيَقُولُنَّ اللَّهُ﴾

(who created them, they will surely say: "Allah.'') means, they will admit that He Alone is the Creator of all things and He has no partner in that. Yet despite that they still worship others alongside Him who have nothing and are able to do nothing. This is the utmost foolishness and stupidity. Allah says:

﴿فَأَنَّى يُؤْفَكُونَ﴾

(How then are they turned away)
