Muhammad - 47:35

فَلَا تَهِنُوا وَتَدْعُوا إِلَى السَّلْمِ وَأَنتُمُ الْأَعْلَوْنَ وَاللَّهُ مَعَكُمْ وَلَن يَتِرَكُمْ أَعْمَالَكُمْ
[47:35]
And be not slack so as to cry for peace and you have the upper hand, and Allah is with you, and He will not bring your deeds to naught.
Be not weary and faint-hearted, crying for peace, when ye should be uppermost: for Allah is with you, and will never put you in loss for your (good) deeds.
So do not falter and cry out for peace when ye (will be) the uppermost, and Allah is with you, and He will not grudge (the reward of) your actions.
