Wise sayings as the believer's lost treasure
Nahj al-Balāgha|Volume 1|Book 3|Chapter 80
٨٠. وَقَالَ (عليه السلام): الْحِكْمَةُ ضَالَّةُ الْمُؤْمِنِ فَخُذِ الْحِكْمَةَ وَلَوْ مِنْ أَهْلِ النِّفَاقِ.
80. Amīr al-mu’minīn, peace be upon him, said: A wise saying is a lost article of the believer. Therefore, get wise sayings even though from people of hypocrisy.
