However, according to Abdul-Rahim, "the earliest extant materials ever written" on the "tafsir" genre, naskh al-Qur’an came earlier than Malik. The two works — "Kitab al-Nasikh wa al-Mansukh fi Kitab Allah Ta‘ala" by Qatadah ibn Di‘amah al-Sadusi (d. 117/735) and "Kitab al-Nasikh wa al-Mansukh" by Muhammad ibn Muslim ibn Shihab al-Zuhri (d. 124/742). — begin "immediately to point to the abrogated in the Qur’an" feeling no need to elucidate what naskh is. According to Abdul-Rahim, the fact that these and other early works followed this practice indicates a "widespread understanding of naskh" in the Muslim world at that time.
