Mankind is [generally] most unjust and ungrateful

وَآتَاكُم مِّن كُلِّ مَا سَأَلْتُمُوهُ ۚ وَإِن تَعُدُّوا نِعْمَتَ اللَّـهِ لَا تُحْصُوهَا ۗ إِنَّ الْإِنسَانَ لَظَلُومٌ كَفَّارٌ

“And He gave you from all you asked of Him. 

And if you should count the favor of Allah, you could not enumerate them. 

Indeed, mankind is [generally] most unjust and ungrateful.”

[The Noble Qur’an - Surah Ibrahim 14:34]
