The Peak of Eloquence · Hadith 91 (#Passage #3)

قال السيد الشربف: يريد عليه السلام أنه أُسر في الكفر مرة وفي الاِسلام مرة . وأما قوله: «دل على قومه السيف»، فأراد به: حديثاً كان للاَشعث مع خالد بن الوليد باليمامة، غرّ فيه قومه ومكر بهم حتى أوقع بهم خالد، وكان قومه بعد ذلك يسمو نه «عُرْفَ النار»، وهو اسم للغادر عندهم.

as-Sayyid ar-Raḍī says: This man was arrested once when an unbeliever and once in days of Islam. As for Amīr al-mu’minīn’s words that the man contrived for his own people to be put to sword, the reference herein is to the incident which occurred to al-Ash‘ath ibn Qays in confrontation with Khālid ibn Walid at Yamāmah, where he deceived his people and contrived a trick till Khālid attacked them. After this incident his people nicknamed him “‘Urf an-Nār” which in the parlance stood for traitor.
