وَٱذْكُرُوٓا۟ إِذْ جَعَلَكُمْ خُلَفَآءَ مِنۢ بَعْدِ عَادٍۢ وَبَوَّأَكُمْ فِى ٱلْأَرْضِ تَتَّخِذُونَ مِن سُهُولِهَا قُصُورًۭا وَتَنْحِتُونَ ٱلْجِبَالَ بُيُوتًۭا ۖ فَٱذْكُرُوٓا۟ ءَالَآءَ ٱللَّهِ وَلَا تَعْثَوْا۟ فِى ٱلْأَرْضِ مُفْسِدِينَ
And remember how He made you viceroys after A'ad and gave you station in the earth. Ye choose castles in the plains and hew the mountains into dwellings. So remember (all) the bounties of Allah and do not evil, making mischief in the earth.
