وَما جَعَلَهُ اللَّهُ إِلّا بُشرىٰ وَلِتَطمَئِنَّ بِهِ قُلوبُكُم ۚ وَمَا النَّصرُ إِلّا مِن عِندِ اللَّهِ ۚ إِنَّ اللَّهَ عَزيزٌ حَكيمٌ

And Allah made it not but good tidings and so that your hearts would be assured thereby. And victory is not but from Allah. Indeed, Allah is Exalted in Might and Wise.
