وهب بن منبه
The research into the life and times of Muhammad, and determining the genuine parts of the sunnah, was an important early reason for scholarship in or about the Arabic language. It was also the reason for the collecting of pre-Islamic poetry; as some of these poets were close to the prophet—Labid meeting Muhammad and converting to Islam—and their writings illuminated the times when these events occurred. Muhammad also inspired the first Arabic biographies, known as A"l-Sirah Al-Nabawiyyah"; the earliest was by Wahb ibn Munabbih, but Muhammad ibn Ishaq wrote the best known. Whilst covering the life of the prophet they also told of the battles and events of early Islam and have numerous digressions on older biblical traditions.
