During his lifetime Musa narrated hadith on the authority of his father, as well as from Ibn Shihab al-Zuhri, Muhammad ibn Munkadir, Yazid ibn Abi Habib, Yazid ibn Abi Mansur, and Hibban ibn Abi Jabalah.[3] He was considered a highly reliable (thiqa thiqa) hadith transmitter by the traditionalist Ahmad ibn Hanbal and "reliable, God willing" (thiqa-in-sha'a llah) by Ibn Sa'd.[4]
