28-25 Ali ibn Abdullah al-Warraq - may God be pleased with him - narrated that Ali ibn Muhammad ibn Mehrawayh al-Qazvini quoted on the authority of Dawood ibn Soleiman al-Qadhi, on the authority of Abil Hassan Ali ibn Musa Al-Ridha (s), on the authority of his father (s), on the authority of his forefathers (s), on the authority of the Commander of the Faithful (s), “The world is all ignorance except for the positions of knowledge. All knowledge is considered to be a proof against man,unless it is acted accordingly. All acts are out of hypocrisy, unless they are done sincerely. Sincerity is subject to danger unless a servant (i.e. a person) ponders over what his final ending will be.”
