Sura 48 Al-Fath (The Victory), ayah 21

1. وَأُخْرَىٰ لَمْ تَقْدِرُوا عَلَيْهَا قَدْ أَحَاطَ اللَّهُ بِهَا ۚ وَكَانَ اللَّهُ عَلَىٰ كُلِّ شَيْءٍ قَدِيرًا

   And (He promises) other (victories) that you were (so far) unable to (realize) which Allah has already encompassed. And ever is Allah, over all things, competent.

   48:21
