اَلْجَامِعَةِ 2:11

ثُمَّ ٱلْتَفَتُّ أَنَا إِلَى كُلِّ أَعْمَالِي ٱلَّتِي عَمِلَتْهَا يَدَايَ، وَإِلَى ٱلتَّعَبِ ٱلَّذِي تَعِبْتُهُ فِي عَمَلِهِ، فَإِذَا ٱلْكُلُّ بَاطِلٌ وَقَبْضُ ٱلرِّيحِ، وَلَا مَنْفَعَةَ تَحْتَ ٱلشَّمْسِ.

Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.
