It is narrated from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that he asked Sayyiduna Zayd bin Thabit (may Allah be pleased with him): "O Zayd bin Thabit! Do you not know that among the verses (of the Noble Qur'an) that we used to recite, we also used to read: 'Do not turn away from your true forefathers (that is, do not abandon them and ascribe yourselves to others), for doing so is kufr (grave ingratitude or sin) on your part'?" He replied: "Yes indeed (I know it well)."
These words are among the blessed verses whose recitation has been abrogated; that is why they are not included in the present mushaf, but their scholarly mention is preserved in the books of hadith and athar.
