The life of Muhammad, his life in a few lines... from Adb Ar Rahman As-Sa'di:

Know that the story of the life of our Prophet Muhammad (SWS) is the most precious aid to know the exegesis of the Book of Allah. The Quran was revealed according to the circumstances of his life, what he said to people and those they answered him. Hence the wisdom of its revelation in a fractional way.

It was Allah who purified his heart and his person and made him perfect. thus among the illustrations of his deep attachment to that which draws closer to Allah, there is the fact that he went to the cave of Hirâ frequently, taking with him food which he intended for the poor.

And there he devoted himself to) prayer and worship, his heart in close relationship with his Lord. He accomplished in acts of devotion what his science allowed him to accomplish in these times of ignorance.
