And they said, "If the Most Merciful had willed, we would not (43:20)

Almuntakhab Fi Tafsir Alquran Alkarim

And they allegedly say: Had Allah, AL-Rahman, so willed we would never have worshipped -these corporate deities-. They are not acquainted with the truth nor do they have information or proof to support their allegation; they simply lic and indeed they lie in their teeth

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(43:20) They say: 'Had the Merciful One so willed, we would never have worshipped these deities.' *20 But they have no knowledge of the matter and are simply conjecturing.

And they said, "If the Most Merciful had willed, we would not meaning

*20) This was their reasoning from destiny to cover up their deviation and error, and this has been the argument of the wrong-doers in every age. They argued that their worshipping the angels became possible only because Allah allowed them to do so. Had He not willed so they could not have done it; and then it had been a practice with them for centuries and no torment from Allah had descended on them, which meant that Allah did not disapprove of their this practice.

یہ کہتے ہیں "اگر خدائے رحمٰن چاہتا (کہ ہم اُن کی عبادت نہ کریں) تو ہم کبھی اُن کو نہ پوجتے" یہ اس معاملے کی حقیقت کو قطعی نہیں جانتے، محض تیر تکے لڑاتے ہیں
