Surah Az-Zukhruf (The Ornaments of Gold), Verse 17

وَاِذَا بُشِّرَ اَحَدُهُمْ بِمَا ضَرَبَ لِلرَّحْمٰنِ مَثَلًا ظَلَّ وَجْهُهٗ مُسْوَدًّا وَّهُوَ كَظِیْمٌ ۟

Wa izaa bushshira ahaduhum bimaa daraba lir Rahmaani masalan zalla wajhuhoo muswaddanw wa huwa kazeem

“When news is brought to one of them of (the birth of) what he sets up as a likeness to (Allah) Most Gracious, his face darkens, and he is filled with inward grief!”

Quran 43:17 (Yusuf Ali Translation)
