Verse 7

إِنْ أَحْسَنتُمْ أَحْسَنتُمْ لِأَنفُسِكُمْ وَإِنْ أَسَأْتُمْ فَلَهَا فَإِذَا جَآءَ وَعْدُ ٱلْـَٔاخِرَةِ لِيَسُـۥٓـُٔوا۟ وُجُوهَكُمْ وَلِيَدْخُلُوا۟ ٱلْمَسْجِدَ كَمَا دَخَلُوهُ أَوَّلَ مَرَّةٍ وَلِيُتَبِّرُوا۟ مَا عَلَوْا۟ تَتْبِيرًا

If you do good, you do good for yourselves, and if you commit evil, then you will see its results. Then when the other promise is fulfilled, disappointment covers your faces and they enter the Mosque, just like they entered the first time, and they wipe out all the gains you had made.
