Surah An-Nisa · Ayah 104

وَلَا تَهِنُوا۟ فِى ٱبْتِغَآءِ ٱلْقَوْمِ ۖ إِن تَكُونُوا۟ تَأْلَمُونَ فَإِنَّهُمْ يَأْلَمُونَ كَمَا تَأْلَمُونَ ۖ وَتَرْجُونَ مِنَ ٱللَّهِ مَا لَا يَرْجُونَ ۗ وَكَانَ ٱللَّهُ عَلِيمًا حَكِيمًا

Wa laa tahinoo fibtighaaa'il qawmi in takoonoo taalamoona fa innahum yaalamoona kamaa taalamoona wa tarjoona minal laahi maa laa yarjoon; wa kaanal laahu 'Aleeman Hakeemaa

And do not weaken in pursuit of the enemy. If you should be suffering - so are they suffering as you are suffering, but you expect from Allah that which they expect not. And Allah is ever Knowing and Wise.
