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.
The Saheeh International Quran Translation
وَمَا جَعَلَهُ ٱللَّهُ إِلَّا بُشْرَىٰ وَلِتَطْمَئِنَّ بِهِۦ قُلُوبُكُمْ وَمَا ٱلنَّصْرُ إِلَّا مِنْ عِندِ ٱللَّهِ إِنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌAnd 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.
