Abu Hamid al-Ghazālī,
Al-Ghazali letter to the Qadi Imam Sa'eed Imadud-din Muhammad Al Wazzan
“ All believers are like one's self united on the basis of piety and relationship in knowledge, acquaintance with one another and cooperation among themselves. Among many treasures, the pearl of the greatest price is the knowledge we have of the early Muslims who recognized Allah as the Causer of all causes and relied fully upon Him, rather than upon their own energy and effort, or upon worldly things. Those indeed are the wisest of men who act in accordance with the preaching and actions of early Muslims. ”
