وَلَا تَهِنُواْ فِي ٱبۡتِغَآءِ ٱلۡقَوۡمِۖ إِن تَكُونُواْ تَأۡلَمُونَ فَإِنَّهُمۡ يَأۡلَمُونَ كَمَا تَأۡلَمُونَۖ وَتَرۡجُونَ مِنَ ٱللَّهِ مَا لَا يَرۡجُونَۗ وَكَانَ ٱللَّهُ عَلِيمًا حَكِيمًا ١٠٤
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 Allāh that which they expect not. And Allāh is ever Knowing and Wise.
Translation: Saheeh International (English)
Each word's meaning and sound
Do not become weak and lazy, O believers, in pursuing your disbelieving enemy. If you are suffering pain because of the killing and injury that afflicts you, then they too are suffering the same pain as well. So do not let their patience be greater than yours, because you have hope of reward, help and support from Allah, which they cannot hope for. Allah knows the conditions of His servants and is Wise in His planning and legislation.
