وَإِذْ قَالَ إِبْرَٰهِۦمُ رَبِّ ٱجْعَلْ هَٰذَا بَلَدًا ءَامِنًۭا وَٱرْزُقْ أَهْلَهُۥ مِنَ ٱلثَّمَرَٰتِ مَنْ ءَامَنَ مِنْهُم بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ ۖ قَالَ وَمَن كَفَرَ فَأُمَتِّعُهُۥ قَلِيلًۭا ثُمَّ أَضْطَرُّهُۥٓ إِلَىٰ عَذَابِ ٱلنَّارِ ۖ وَبِئْسَ ٱلْمَصِيرُ
And when Abraham prayed: My Lord! Make this a region of security and bestow upon its people fruits, such of them as believe in Allah and the Last Day, He answered: As for him who disbelieveth, I shall leave him in contentment for a while, then I shall compel him to the doom of Fire - a hapless journey's end!
