Client of Family of Az-Zubair Al-Awaam.
He wrote a book on Maghaazi. A fragment of his work has survived and was published by Sachau in 1904, the so-called Berlin manuscript. Many distinguished traditionists felt his book was the most important and trustworthy of all, rivaling that of his contemporary Ibn Ishaq, and yet, surprisingly, not much of his work has survived. Ibn Ishaq himself never mentions him, though he is quoted by later historians like al-Tabari, al-Waqidi, and others. Musa for his part leaned heavily on al-Zuhri, much idealizing the Prophet.
