Sura 3 Ali 'Imran (Family of Imran), aya 128

1. لَيْسَ لَكَ مِنَ الْأَمْرِ شَيْءٌ أَوْ يَتُوبَ عَلَيْهِمْ أَوْ يُعَذِّبَهُمْ فَإِنَّهُمْ ظَالِمُونَ

   Not for you, (O Muhammad, but for Allah), is the decision whether He should (cut them down) or forgive them or punish them, for indeed, they are wrongdoers.

   3:128
