43:17
وَإِذَا بُشِّرَ أَحَدُهُم بِمَا ضَرَبَ لِلرَّحْمَٰنِ مَثَلًۭا ظَلَّ وَجْهُهُۥ مُسْوَدًّۭا وَهُوَ كَظِيمٌ
And when one of them is given good tidings of that which he attributes to the Most Merciful in comparison, his face becomes dark, and he suppresses grief.

But the share of their partners reaches not Allah, while the share of Allah reaches their partners! Evil is the way they judge!) (6:136). Similarly, out of the two kinds of offspring, sons and daughters, they assigned to Him the worst and least valuable (in their eyes), i.e., daughters, as Allah says:

(Is it for you the males and for Him the females That indeed is a division most unfair!) (53:21-22) And Allah says here:
