The horse itself is its teeths ---- إن الجواد عينه فراره

  The word “farar” (with a kasra) means looking at the teeth of an animal to determine its age. It is a verbal noun, and from it comes the saying of Al-Hajjaj: “I fled from intelligence.” It is narrated as “fararah” (with a damma), and it is a noun derived from it. It is used to describe someone whose outward appearance indicates his inner self, thus making testing him unnecessary. It is even said that the evil person’s very essence is his “fararah.”

الفرار بالكسر النظر إلى أسنان الدابة لتعرف قدر سنها وهو مصدر ومنه قول الحجاج فررت عن ذكاء ويروى فراره بالضم وهو اسم منه يضرب لمن يدل ظاهره على باطنه فيغني عن اختباره حتى لقد يقال إن الخبيث عينه فراره.

The unfortunate one is a newcomer to the broom ---- إن الشقي وافد البرجم

a term used to describe someone who brings destruction upon himself out of greed.

 This was said by Amr ibn Hind, the king. Suwaid ibn Rabi'ah al-Tamimi killed his brother and fled, so he burned one hundred men from Tamim, ninety-nine from Banu Darim, and one from al-Barajim. He was thus nicknamed al-Muharriq (the Burner). The full story will be told in the chapter on the letter Sad. Al-Harith ibn Amr, the king of Syria from the Banu Jafnah, was also called al-Muharriq because he was the first to burn Arabs in their homes. Imru' al-Qays ibn Amr ibn Adi al-Lakhmi was also called al-Muharriq,

قاله عمرو بن هند الملك وكان سويد بن ربيعة التميمي قتل أخاه وهرب فأحرق به مائة من تميم وتسعة وتسعين من بني دارم وواحداً من البراجم فلقب بالمحرق وستأتي القصة بتمامها في باب الصاد. وكان الحرث بن عمر وملك الشأم من آل جفنة يدعى أيضاً بالمحرق لأنه أول من حرق العرب في ديارهم. ويدعى امرؤ القيس بن عمرو بن عدي اللخمي محرقاً أيضاً يضرب لمن يوقع نفسه في هلكة طمعاً
