I love this Arab saying,
“حرقت قلبي”
- You burnt my heart.
The feeling you get when someone you love is in pain and you're helpless; you can't do anything to ease their pain. Your feeling is literally described as holding your heart in flames.
وَقَٰتِلُواْ فِي سَبِيلِ ٱللَّهِ ٱلَّذِينَ يُقَٰتِلُونَكُمۡ وَلَا تَعۡتَدُوٓاْۚ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلۡمُعۡتَدِينَ
Fight in the way of Allah against those who fight you, and do not transgress. Verily, Allah does not like the transgressors.
Al-Qur'an 2:190
