Sura 8 Al-Anfal (The Spoils of War), ayat 19

1. إِنْ تَسْتَفْتِحُوا فَقَدْ جَاءَكُمُ الْفَتْحُ ۖ وَإِنْ تَنْتَهُوا فَهُوَ خَيْرٌ لَكُمْ ۖ وَإِنْ تَعُودُوا نَعُدْ وَلَنْ تُغْنِيَ عَنْكُمْ فِئَتُكُمْ شَيْئًا وَلَوْ كَثُرَتْ وَأَنَّ اللَّهَ مَعَ الْمُؤْمِنِينَ

   If you (disbelievers) seek the victory - the defeat has come to you. And if you desist (from hostilities), it is best for you; but if you return (to war), We will return, and never will you be availed by your (large) company at all, even if it should increase; and (that is) because Allah is with the believers.

   8:19
