Part of a statement by ʿAlī, may Allah be pleased with him, reads:
حَدِّثُوا النَّاسَ بِمَا يَعْرِفُونَ (Sahih al-Bukhari: 127)
Translation: Speak to people about what they can understand.
• These are ʿAlī's own words.
• ʿAlī is a Companion.
• This is therefore an example of a mawqūf (موقوف) report: it conveys a Companion's own statement.
