Hadith Commentary: Benefits and Issues: Muzaynah, Juhaynah, Ghifar, Ashja‘, and the clan of Ghatfan known as Banu ‘Abd al-‘Uzza, whom the Messenger of Allah (sallallahu alayhi wa sallam) named Banu ‘Abdullah, in the era of ignorance (Jahiliyyah), were considered inferior in terms of honor, status, and strength compared to Banu ‘Amir ibn Sa‘sa‘ah, Banu Tamim, and others. However, when they took the lead in embracing Islam, they attained a position of honor and elevation, and the previously honored and powerful tribes of Jahiliyyah were left behind.
