al-Sharif al-Radi (d. 406 AH) · Thaqalayn library edition, reproduced verbatim
٤٥٨. وَقَالَ (عليه السلام): (عَلَامَةُ) الْإِيمَانُ أَنْ تُؤثِرَ الصِّدْقَ حَيْثُ يَضُرُّكَ عَلَى الْكَذِبِ حَيْثُ يَنْفَعُكَ، وَأَلَّا يَكُونَ فِي حَديِثِكَ فَضْلٌ عَنْ عِلْمِكَ وَأَنْ تَتَّقِيَ اللهَ فِي حَدِيثِ غَيْرِكَ.
458. Amīr al-mu’minīn, peace be upon him, said: Belief means that you should prefer truth (even) when it harms you rather than falsehood (even) when it benefits you; that your words should not be more than your action and that you should fear Allāh when speaking about others.
