وَإِذَا بُشِّرَ أَحَدُهُم بِمَا ضَرَبَ لِلرَّحْمَـٰنِ مَثَلًا ظَلَّ وَجْهُهُۥ مُسْوَدًّا وَهُوَ كَظِيمٌ

Wa-itha bushshira ahaduhum bimadaraba lirrahmani mathalan thallawajhuhu muswaddan wahuwa katheem

And when one of them is given good tidings of that which he attributes to the Most Merciful in comparison [i.e., a daughter], his face becomes dark, and he suppresses grief.
