﴿ أَمِ ٱتَّخَذَ مِمَّا يَخْلُقُ بَنَاتٍۢ وَأَصْفَىٰكُم بِٱلْبَنِينَ ﴾

“Or [do you think], perchance, that out of all His creation He has chosen for Himself daughters, and favoured you with sons?”

Or am has the significance of the hamza of denial; the ‘saying’ is implied in other words a-taqūlūna ‘or do you say that …’ He has adopted from all that He has created daughters for Himself and preferred you privileged you with sons? — that which is the necessary inference from what you claim and which by itself is an abomination.
