Islamic ethics (أخلاق إسلامية), defined as "good character," historically took shape gradually from the 7th century and was finally established by the 11th century. It was eventually shaped as a successful amalgamation of the Qur'anic teachings, the teachings of the Sunnah of Muhammad, the precedents of Islamic jurists (see Sharia and Fiqh), the pre-Islamic Arabian tradition, and non-Arabic elements (including Persian and Greek ideas) embedded in or integrated with a generally Islamic structure. Although Muhammad's preaching produced a "radical change in moral values based on the sanctions of the new religion and the present religion, and fear of God and of the Last Judgment", the tribal practice of Arabs did not completely die out. Later Muslim scholars expanded the religious ethic of the Qur'an and Hadith in immense detail.
