The strong one controls themselves in anger
لَيْسَ الشَّدِيدُ بِالصُّرَعَةِ، إِنَّمَا الشَّدِيدُ الَّذِي يَمْلِكُ نَفْسَهُ عِنْدَ الْغَضَبِ
Laysa-sh-shadidu bi-s-sura'ah, innama-sh-shadidu-lladhi yamliku nafsahu 'inda-l-ghadab.
"The strong one is not the one who overpowers others in wrestling. The strong one is the one who controls himself when angry."
Narrated by Abu Hurayrah. Sahih al-Bukhari 6114, Sahih Muslim 2609
A short reflection
Re-definition. The real lift is not at the gym, it's holding your tongue when your pride is on fire.
