﴿ إِنْ أَحْسَنتُمْ أَحْسَنتُمْ لِأَنفُسِكُمْ ۖ وَإِنْ أَسَأْتُمْ فَلَهَا ۚ فَإِذَا جَآءَ وَعْدُ ٱلْءَاخِرَةِ لِيَسُۥٓـُٔوا۟ وُجُوهَكُمْ وَلِيَدْخُلُوا۟ ٱلْمَسْجِدَ كَمَا دَخَلُوهُ أَوَّلَ مَرَّةٍۢ وَلِيُتَبِّرُوا۟ مَا عَلَوْا۟ تَتْبِيرًا ﴾

“[And We said:] "If you persevere in doing good, you will but be doing good to yourselves; and if you do evil, it will be [done] to yourselves." And so, when the prediction of the second [period of your iniquity] came true, [We raised new enemies against you, and allowed them] to disgrace you utterly, and to enter the Temple as [their forerunners] had entered it once before, and to destroy with utter destruction all that they had conquered.”
