Human ingratitude and arrogance

أَوَلَمْ يَرَ ٱلْإِنسَـٰنُ أَنَّا خَلَقْنَـٰهُ مِن نُّطْفَةٍ فَإِذَا هُوَ خَصِيمٌ مُّبِينٌ

Does man not consider that We created him from a [mere] sperm-drop - then at once he is a clear adversary?

وَإِذَآ أَنْعَمْنَا عَلَى ٱلْإِنسَـٰنِ أَعْرَضَ وَنَـَٔا بِجَانِبِهِۦ وَإِذَا مَسَّهُ ٱلشَّرُّ فَذُو دُعَآءٍ عَرِيضٍ

And when We bestow favor upon man, he turns away and distances himself; but when evil touches him, then he is full of extensive supplication.
