Allah (Glorified and Exalted is He) told us in Quran that the Muhammad (peace be upon him) did not speak from his own: “Your companion (Muhammad) is neither astray, nor misguided, nor does he speak out of his own desire.

The life of the Prophet Muhammad (peace be upon him) is the example to follow, we have been told by Allah (Glorified and Exalted is He) to follow the example of His messenger (peace be upon him). “Verily in the messenger of Allah (Muhammad) you have a good example to follow.” (Nobel Quran 33, 21).

The tradition (Sunnah) of the entire life of the Prophet Muhammad (peace be upon him) has been recorded in books and preserved until today. All what a man might need in his daily life is found in these books.
