Surah As-Saffah (Those Angels Lines up in Ranks), Verse 11

فَاسْتَفْتِهِمْ اَهُمْ اَشَدُّ خَلْقًا اَمْ مَّنْ خَلَقْنَا اِنَّا خَلَقْنٰهُمْ مِّنْ طِیْنٍ لَّازِبٍ ۟

Fastaftihim ahum ashaddu khalqan am man khalaqnaa; innaa khalaqnaahum min teenil laazib

“Just ask their opinion: are they the more difficult to create, or the (other) beings We have created? Them have We created out of a sticky clay!”

Quran 37:11 (Yusuf Ali Translation)
