تَدَارَكْتُمَا عَبْسًا وَذُبْيَانَ بَعْدَمَا ۞ تَفَانَوْا وَدَقُّوا بَيْنَهُمْ عِطْرَ مَنْشِمِ
Meaning: You two rescued ʿAbs and Dhubyān after they had nearly destroyed each other and their feud had reached the deadly intensity of the perfume of Manshim.
Tadāraktumā (form VI) means that the two men caught the situation in time and repaired it. ʿAbsan wa-Dhubyāna are its objects. Tafānaw expresses mutual destruction or severe depletion through warfare.
ʿIṭr Manshim is an established proverbial reference to deadly fighting; the commentary records explanations of its background. Its immediate poetic function is to evoke the intensity of a blood feud, not ordinary agreeable perfume.
