Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "The Final Hour will not come until people compete with one another in the height of their buildings."  

عَنْ رَسُولِ اللهِ ﷺ قَالَ لاَ تَقُومُ السَّاعَةُ حَتَّى يَتَطَاوَلَ النَّاسُ فِي الْبُنْيَانِ  

Al-Hasan said, "I used to go into the houses of the wives of the Prophet, may Allah bless him and grant him peace, during the khalifate of 'Uthman ibn 'Affan, and I could touch their ceilings with my own hand."  

سَمِعْتُ الْحَسَنَ يَقُولُ كُنْتُ أَدْخُلُ بُيُوتَ أَزْوَاجِ النَّبِيِّ ﷺ فِي خِلاَفَةِ عُثْمَانَ بْنِ عَفَّانَ فَأَتَنَاوَلُ سُقُفَهَا بِيَدِي  

Dawud ibn Qays said, "I saw that the rooms were made from the stumps of palm trees covered on the outside with smoothed hair. I think that the width of the house from the door of the room to the door of the house was about six or seven spans. The width of the room inside was ten spans. I think that the ceiling was between seven and eight, or there about. I stopped at the door of 'A'isha, which was facing the west."  

أَخْبَرَنَا دَاوُدُ بْنُ قَيْسٍ قَالَ رَأَيْتُ الْحُجُرَاتِ مِنْ جَرِيدِ النَّخْلِ مَغْشِيًّا مِنْ خَارِجٍ بِمُسُوحِ الشَّعْرِ وَأَظُنُّ عَرْضَ الْبَيْتِ مِنْ بَابِ الْحُجْرَةِ إِلَى بَابِ الْبَيْتِ نَحْوًا مِنْ سِتِّ أَوْ سَبْعِ أَذْرُعٍ وَأَحْزِرُ الْبَيْتَ الدَّاخِلَ عَشْرَ أَذْرُعٍ وَأَظُنُّ سُمْكَهُ بَيْنَ الثَّمَانِ وَالسَّبْعِ نَحْوَ ذَلِكَ وَوَقَفْتُ عِنْدَ بَابِ عَائِشَةَ فَإِذَا هُوَ مُسْتَقْبِلٌ الْمَغْرِبَ  

"Do not make your buildings tall. That will come about in the worst of your days."'"  

أَنْ لاَ تُطِيلُوا بِنَاءَكُمْ فَإِنَّهُ مِنْ شَرِّ أَيَّامِكُمْ
