Mishkat al-Masabih #232

Ibrahim b. ‘Abd ar-Rahman al-‘Udhri reported God's messenger as saying, "In every successive century those who are reliable authorities will preserve this knowledge, rejecting the changes made by extremists, the plagiarisms of those who make false claims for themselves, and the interpretations of the ignorant.”* *The source is lacking. The editor of the Damascus edition of the Mishkat says the tradition is given by Baihaqi in al-Madkhal.
