﴿ وَمَا جَعَلَهُ ٱللَّهُ إِلَّا بُشْرَىٰ وَلِتَطْمَئِنَّ بِهِۦ قُلُوبُكُمْ ۚ وَمَا ٱلنَّصْرُ إِلَّا مِنْ عِندِ ٱللَّهِ ۚ إِنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌ ﴾

And God appointed it that is the reinforcement only as good tidings and that your hearts might thereby be reassured. Victory comes only from God surely God is Mighty Wise.
