Mishkat al-Masabih 30 Fine Qualities كتاب المناقب 12

وَعَن أبي عَامر الْأَشْعَرِيِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «نَعْمَ الْحَيُّ الْأَسْدُ وَالْأَشْعَرُونَ لَا يَفِرُّونَ فِي الْقِتَالِ وَلَا يَغُلُّونَ هُمْ مِنِّي وَأَنَا مِنْهُمْ» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ

Abu `Amir al-Ash`ari reported God’s messenger as saying, “Asad and the members of Ash’ar[*] are good. They do not fly when fighting and are not treacherous. They pertain to me and I to them.” * Mirqat , 5:511, suggests the reading Asd and says that both Ash’aruna and Ash’ariyuna are used. It says the former here refers to Azd Shanu’a. But there was a branch of Quraish called Asad. Tirmidhi transmitted it, saying this is a gharib tradition.
