Hardship's inevitability and prayer's necessity
Nahj al-Balāgha|Volume 1|Book 3|Chapter 302
٣٠٢. وَقَالَ (عليه السلام): مَا الْمُبْتَلَى الَّذِي قَدِ اشْتَدَّ بِهِ الْبَلاَءُ، بِأَحْوَجَ إِلَى الدُّعَاءِ مِنَ المُعَافَى الَّذِي لَا يَأمَنُ البَلاَءَ.
302. Amīr al-mu’minīn, peace be upon him, said: The person who is afflicted with hardship is not in greater need of praying than the one who has been spared affliction but is not immune from it.
