Allah says:وَمَا هَذِهِ الْحَيَاةُ الدُّنْيَا إِلاَّ لَهْوٌ وَلَعِبٌAnd this life of the world is only an amusement and a play!Allah tells us how insignificant and transient this world is, and how it will soon end. All that it is, is amusement and play:وَإِنَّ الدَّارَ الاْإخِرَةَ لَهِيَ الْحَيَوَانُVerily, the home of the Hereafter -- that is the life indeed,means, the true everlasting life that will never end, but will continue forever and ever.لَوْ كَانُوا يَعْلَمُونَif they but knew.means, they would prefer that which will last over that which will pass away.Then Allah says that at times of calamity, the idolators call upon Him alone, with no partner or associate, so why do they not do that all the time!
