قَالُوٓا۟ أُوذِينَا مِن قَبْلِ أَن تَأْتِيَنَا وَمِنۢ بَعْدِ مَا جِئْتَنَا ۚ قَالَ عَسَىٰ رَبُّكُمْ أَن يُهْلِكَ عَدُوَّكُمْ وَيَسْتَخْلِفَكُمْ فِى ٱلْأَرْضِ فَيَنظُرَ كَيْفَ تَعْمَلُونَ
They said: We suffered hurt before thou camest unto us, and since thou hast come unto us. He said: It may be that your Lord is going to destroy your adversary and make you viceroys in the earth, that He may see how ye behave.
