٢٧٤. وَقَالَ (عليه السلام): لَا تَجْعَلُوا عِلْمَكُمْ جَهْلًا وَيَقِينَكُمْ شَكّاً إِذَا عَلِمْتُمْ فَاعْمَلُوا وَإِذَا تَيَقَّنْتُمْ فَأَقْدِمُوا.
274. Amīr al-mu’minīn, peace be upon him, said: Do not turn your knowledge into ignorance or your conviction into doubt. When you gain knowledge act (upon it) and when you acquire conviction proceed (on its basis). [1]
