Qur'an 37:11 · As-Saaffaat

فَٱسْتَفْتِهِمْ أَهُمْ أَشَدُّ خَلْقًا أَم مَّنْ خَلَقْنَآ ۚ إِنَّا خَلَقْنَٰهُم مِّن طِينٍۢ لَّازِبٍۭ

(11) Then inquire of them, [O Muḥammad], "Are they a stronger [or more difficult] creation or those [others] We have created?" Indeed, We created them [i.e., men] from sticky clay.
