Hisham bin Urwah narrated from his father that he said: "Sometimes I hear a hadith and I like it, but I do not narrate it because someone who hears it might act upon it, while I have heard it from a person whom I do not consider reliable, even though he has narrated it from someone whom I do consider reliable. And sometimes I hear it from a trustworthy person while he is narrating it from someone who is not trustworthy." Sa‘d bin Ibrahim said: "No one should narrate hadiths from the Prophet ﷺ except trustworthy narrators."
