Surah Yunus, Ayat 24

Ayat 24. Verily the likeness of (this) worldly life is as the water (rain) which We send down from the sky, so by it arises the intermingled produce of the earth of which men and cattle eat until when the earth is clad with its adornments and is beautified, and its people think that they have all the powers of disposal over it, Our Command reaches it by night or by day and We make it like a clean-mown harvest, as if it had not flourished yesterday! Thus do We explain the Ayat (proofs, evidences, verses, lessons, signs, revelations, laws, etc.) in detail for the people who reflect. 

Hazrat Shaddad bin Aus (May Allah be pleased with him) reported: The Messenger of Allah  [SAWW](PBUH) said, "A wise man is the one who calls himself to account (and refrains from doing evil deeds) and does noble deeds to benefit him after death; and the foolish person is the one who subdues himself to his temptations and desires and seeks from Allah the fulfillment of his vain desires". [At-Tirmidhi Hadith # 2459].  

Lesson : as mentioned above in Surah Yunus Ayat 24. "We explain the Ayat (proofs, evidences, verses, lessons, signs, revelations, laws, etc.) in detail for the people who reflect". This Hadith highlights the importance of the accountability of one's self. Mere desires which are not coupled with practical efforts are of no avail because Allah grants reward on good deeds and not on yearnings and desires which are not supported by noble actions.
