(این از سخنان ارزشمند و شگفتی آور است، که عاقل زبانش را بدون مشورت و فکر و سنجش رها نمی ساز، اما احمق هرچه بر زبانش آید می گوید بدون فکر و… Amir al-Mu'minin, peace be upon him, said: The tongue of the wise man is behind his heart, and the heart of the fool is behind his tongue.…

وَ قَالَ (عليه السلام): لِسَانُ الْعَاقِلِ وَرَاءَ قَلْبِهِ وَ قَلْبُ الْأَحْمَقِ وَرَاءَ لِسَانِهِ.

قال الرضي: و هذا من المعاني العجيبة الشريفة و المراد به أن العاقل لا يطلق لسانه إلا بعد مشاورة الروية و مؤامرة الفكرة و الأحمق تسبق حذفات لسانه و فلتات كلامه مراجعة فكره و مماخضة رأيه فكأن لسان العاقل تابع لقلبه و كأن قلب الأحمق تابع للسانه.

Amir al-Mu'minin, peace be upon him, said: The tongue of the wise man is behind his heart, and the heart of the fool is behind his tongue. Al-Sayyid al-Radi says: This sentence has a special and beautiful meaning. It means that the wise man does not speak with his tongue except after consulting his mind and exercising his imagination, but the fool quickly utters whatever comes to his tongue without thinking. In this way, the tongue of the wise man follows his heart while the heart of the fool follows his tongue
