Surah 102. Al-Takathur, Ayah 2

The term takathur bears the connotation of "greedily striving for an increase," i.e., in benefits, be they tangible or intangible, real or illusory. In the above context it denotes man's obsessive striving for more and more comforts, more material goods, greater power over his fellow-men or over nature, and unceasing technological progress. A passionate pursuit of such endeavours, to the exclusion of everything else, bars man from all spiritual insight and, hence, from the acceptance of any restrictions and inhibitions based on purely moral values - with the result that not only individuals but whole societies gradually lose all inner stability and, thus, all chance of happiness.

 lit., visited the graves, since the stay in the grave is brief, followed by eternal life either in Paradise or Hell.

That is, until the time comes when you must lie down in the graves and leave and pomp and circumstance of an empty life. The true Reality will then appear before you. Why not try to strive for a little understanding of that Reality in this very life?
