Sheikh, from a Hadith we can know that one of the sign of Qiyamah is the competition for constructing Skyscrapers specially among Arab people. And nowadays we see that it is real. My question is should we everyone or Arabs avoid our desire for aristocrat skyscrapers? Or how can we understand that Hadith?
