Al-Ghazali

Abū Ḥāmid Muḥammad ibn Muḥammad al-Ghazālī, shortened as Al-Ghazali in Arabic or Ghazali in Persian and known as Algazelus or Algazel to the Western medieval world, was a Muslim theologian, jurist, philosopher, and mystic of Persian descent. Al-Ghazali has been referred to by some historians as the single most influential Muslim after the Islamic prophet Muhammad.[16] Within Islamic civilization he is considered to be a Mujaddid or renewer of the faith, who, according to tradition, appears once every century to restore the faith of the community.
