Read and reflect on verse 3799 from Surah As-Saaffaat: AND NOW ask those [who deny the truth] to enlighten thee: Were they more difficult to create than all those [untold marvels] that We have created? - ...
فَاسْتَفْتِهِمْ أَهُمْ أَشَدُّ خَلْقًا أَمْ مَنْ خَلَقْنَا ۚ إِنَّا خَلَقْنَاهُمْ مِنْ طِينٍ لَازِبٍ
AND NOW ask those [who deny the truth] to enlighten thee: Were they more difficult to create than all those [untold marvels] that We have created? - for, behold, them have We created out of [mere] clay commingled with water!
