The question of whether not just some but "all" abrogated verses ("mansukh") were deleted from the "mushaf", (meaning that contrary to scholarly consensus, there is no "classic" mode of naskh, no #1. "naskh al-hukm dūna al-tilāwa", because nothing included in the "mushaf" has been abrogated, no "mansukh" is found there) has been raised by Roslan Abdul-Rahim. A Bukhari hadith about second caliph 'Umar ignoring Ubai recitations including "revelations that had allegedly been abrogated", indicates early Muslims ignored verses that had been abrogated, so that these verses would not have found their way into the "Mushaf".
