The prophetic ethics and the courtesies of living

In the Book of Prophetic Ethics and the Courtesies of Living (Kitab Adab al ma' isha wa-akhlaq al-nubuwwa), book twenty of the forty books which compose the Revival of the Religious Sciences (Ihya' ' ulum al-din), Abu hamid al-Ghazali gives a full account of the customs and character of the Messenger of God, Muhammad. It is not a biography of Muhammad (peace and blessing of God be upon him) but a roadmap for those who want to strengthen their faith, increase their knowledge and deepen their understanding of the second part of the testimony of faith, namely the first pillar of Islam.
