وَلَا تَهِنُوا فِي ابْتِغَاءِ الْقَوْمِ ۖ إِنْ تَكُونُوا تَأْلَمُونَ فَإِنَّهُمْ يَأْلَمُونَ كَمَا تَأْلَمُونَ ۖ وَتَرْجُونَ مِنَ اللَّهِ مَا لَا يَرْجُونَ ۗ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا 104
And slacken not in following up the enemy: If ye are suffering hardships, they are suffering similar hardships; but ye have Hope from Allah, while they have none. And Allah is full of knowledge and wisdom.
