Qur'an 9:14

قَـٰتِلُوهُمْ يُعَذِّبْهُمُ ٱللَّهُ بِأَيْدِيكُمْ وَيُخْزِهِمْ وَيَنصُرْكُمْ عَلَيْهِمْ وَيَشْفِ صُدُورَ قَوْمٍ مُّؤْمِنِينَ

Fight them! Allah will chastise them at your hands, and He will lay them low and give you victory over them, and He will heal the breasts of folk who are believers.
