وَإِذَا And when بُشِّرَ is given good news أَحَدُهُم (to) one of them بِمَا of what ضَرَبَ he sets up لِلرَّحْمَـٰنِ for the Most Gracious مَثَلًۭا (as) a likeness ظَلَّ becomes وَجْهُهُۥ his face مُسْوَدًّۭا dark وَهُوَ and he كَظِيمٌ (is) filled with grief ١٧
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.
