A mawqūf (موقوف) report is attributed to a Companion: it conveys the Companion's own saying, action or approval.1
• Qawl (قول): the Companion's own words.
• Fiʿl (فعل): the Companion's own action.
• Taqrīr (تقریر): the Companion's approval of an act, or not objecting to it while aware of it.
A mawqūf report is therefore not limited to quoting a Companion's words.
1. Attribution — nisbat (نسبت): Here this means identifying whose words or conduct the report describes.
