"Say, 'Travel through the land; then observe how was the end of the deniers.'" Their end was that Allah destroyed them, then consigned them to the Fire.
﴿قُلْ سِيرُوا فِي الأَرْضِ ثُمَّ انْظُرُوا كَيْفَ كَانَ عَاقِبَةُ الْمُكَذِّبِينَ﴾ كَانَ عاقبتهم أَن دمر الله عَلَيْهِم، ثمَّ صيرهم إِلَى النَّار.
