﴿ وَلَئِن سَأَلْتَهُم مَّنْ خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ لَيَقُولُنَّ ٱللَّهُ ۖ فَأَنَّىٰ يُؤْفَكُونَ ﴾

“And thus it is [with most people]: if thou ask them, “Who is it that has created the heavens and the earth, and made the sun and the moon subservi­ent [to His laws]?” - they will surely answer, “God.” How perverted, then, are their minds!”

And if wa-la-in the lām is for oaths you were to ask them namely the disbelievers ‘Who created the heavens and the earth and disposed the sun and the moon?’ They would assuredly say ‘God.’ So how then are they turned away? from affirming His Oneness after affirming that God created them.
