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

If you happen to suffer pain, behold they suffer pain even as you suffer it: but you are hoping [to receive] from God what they cannot hope for. And God is indeed all-knowing, wise.
 - Mohammad Asad
Do not show weakness in following up the enemy; if you are suffering hardships they too are suffering similar hardships; moreover, you have hope to receive reward from Allah while they have none. Allah is the Knowledgeable, Wise.
 - Muhammad Farooq-i-Azam Malik
Do not falter in pursuit of the enemy- if you are suffering, they too are suffering. But you can hope to receive from Allah what they can never hope for. And Allah is All-Knowing, All-Wise.
 - Mustafa Khattab
Relent not in pursuit of the enemy. If ye are suffering, lo! they suffer even as ye suffer and ye hope from Allah that for which they cannot hope. Allah is ever Knower, Wise.
 - Marmaduke Pickthall
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. 620
