Surah An-Nisa Verse 104 - English Translation by Muhammad Mahmoud Ghali
Surah An-Nisaوَلَا تَهِنُواْ فِي ٱبۡتِغَآءِ ٱلۡقَوۡمِۖ إِن تَكُونُواْ تَأۡلَمُونَ فَإِنَّهُمۡ يَأۡلَمُونَ كَمَا تَأۡلَمُونَۖ وَتَرۡجُونَ مِنَ ٱللَّهِ مَا لَا يَرۡجُونَۗ وَكَانَ ٱللَّهُ عَلِيمًا حَكِيمًا
And do not feel fee bled in seeking the people (i.e., the "enemy" people). In case you feel pain, then surely they (also) feel pain as you feel pain, and you are hoping from Allah that for which they do not hope; and Allah has been Ever-Knowing, Ever-Wise
