Surah Hud (PBUH) : Ayat 123

And to Allah belongs the Ghaib (unseen) of the heavens and the earth, and to Him return all affairs (for decision). So worship Him and put your trust in Him. And your Lord Alalh is not unaware of what you (people) do."     

Hazrat Abdullah bin Masud (May Allah be pleased with him) reported: Messenger of Allah  [SAWW](PBUH) said: "Do not crave for property lest you should be absorbed in the desire of worldly life.'' 

[At-Tirmidhi Hadith # 2328] 

Lesson : as mentioned above in Surah Hud Ayat 123. "And your Lord Alalh is not unaware of what you (people) do." The word "Dai'ah'' translated here as "property'' means land, industry, agriculture or business. One should not be so engrossed in them to the extent that, they become the sole purpose of one's life and all one's efforts are exhausted to acquire them, thus forgetting all about the Hereafter. To the extent of one's genuine needs and self-sufficiency, making and maintaining of property, land, industry, agriculture and commerce come in permissible acts. None of them is forbidden provided the means employed for making and maintaining them are fair and do not distract one's attention from Allah and the Hereafter.
