Endurance proportional to affliction
Nahj al-Balāgha|Volume 1|Book 3|Chapter 144
١٤٤. وَقَالَ (عليه السلام): يَنْزِلُ الصَّبْرُ عَلَى قَدْرِ الْمُصِيبَةِ، وَمَنْ ضَرَبَ يَدَهُ عَلَى فَخِذِهِ عِنْدَ مُصِيبَتِهِ حَبِطَ أجْرُهُ.
144. Amīr al-mu’minīn, peace be upon him, said: Endurance comes according to the affliction. He who beats his hand on the thigh in his affliction ruins all his good actions.
