Virtues of patience, restraint, and submission to Allah
Nahj al-Balāgha|Volume 1|Book 3|Chapter 4
٤. وَقَالَ (عليه السلام): الْعَجْزُ آفَةٌ وَالصَّبْرُ شَجَاعَةٌ وَالزُّهْدُ ثَرْوَةٌ وَالْوَرَعُ جُنَّةٌ وَنِعْمَ الْقَرِينُ الرِّضَى.
4. Amīr al-mu’minīn, peace be upon him, said: Incapability is a catastrophe; endurance is bravery; abstinence is riches; self-restraint is a shield (against sin); and the best companion is submission (to Allāh’s will).
