فأما عاد فاستكبروا في الأرض بغير الحق وقالوا من أشد منا قوة (41:15) بالانجليزي

﴿فَأَمَّا عَادٌ فَاسْتَكْبَرُوا فِي الْأَرْضِ بِغَيْرِ الْحَقِّ وَقَالُوا مَنْ أَشَدُّ مِنَّا قُوَّةً ۖ أَوَلَمْ يَرَوْا أَنَّ اللَّهَ الَّذِي خَلَقَهُمْ هُوَ أَشَدُّ مِنْهُمْ قُوَّةً ۖ وَكَانُوا بِآيَاتِنَا يَجْحَدُونَ﴾
[ فصلت: 15]

As for 'Aad, they were arrogant upon the earth without right and said, "Who is greater than us in strength?" Did they not consider that Allah who created them was greater than them in strength? But they were rejecting Our signs.

Now the 'Ad behaved arrogantly through the land, against (all) truth and reason, and said: "Who is superior to us in strength?" What! did they not see that Allah, Who created them, was superior to them in strength? But they continued to reject Our Signs!
