The Satanic Verses incident is reported in the tafsir and the sira-maghazi literature dating from the first two centuries of Islam, and is reported in the respective tafsīr corpuses transmitted from almost every Qur'anic commentator of note in the first two centuries of the hijra. According to Ibn Taymiyyah: "The early Islamic Scholars (Salaf) collectively considered the Verses of Cranes in accordance with Quran. And from the later coming scholars (Khalaf), who followed the opinion of the early scholars, they say that these traditions have been recorded with authentic chain of narration and it is impossible to deny them, and Quran is itself testifying it. " The earliest biography of Muhammad, Ibn Ishaq (761–767) is lost but his collection of traditions survives mainly in two sources: Ibn Hisham (833) and al-Tabari (915). The story appears in al-Tabari, who includes Ibn Ishaq in the chain of transmission, but not in Ibn Hisham, who admits in the preface of his text that he omitted matters from Ibn Ishaq's biography that "would distress certain people". Ibn Sa'd and Al-Waqidi, two other early biographers of Muhammad relate the story. Scholars such as Uri Rubin and Shahab Ahmed and Guillaume hold that the report was in Ibn Ishaq, while Alford T. Welch holds the report has not been presumably present in the Ibn Ishaq.
