 The movement of a cloud that kept shadowing Muhammad regardless of the time of the day drew Bahira's attention.The monk revealed his visions of Muhammad's future to the boy's uncle (Abu Talib), warning him to preserve the child from the Jews (in Ibn Sa'd's version) or from the Byzantines (in al-Tabari's version).Both Ibn Sa'd and al-Tabari write that Bahira found the announcement of the coming of Muhammad in the original, unadulterated gospels, which he possessed.
