Discussion of the chain of narration of the hadith of 'Abd ibn Mas'ud (may Allah be pleased with both of them): "The worst of the characteristics of a believer is foul language"

The Shaykh : However, this hadith is not marfu' (traced to the Prophet) to the Messenger of Allah (peace and blessings be upon him); rather, it is from the saying of Ibn Mas'ud himself. What did he say? "The worst of the characteristics of a believer is foul language." The worst characteristic that a believer adopts is foul language in speech. This type of hadith is called, in the terminology of hadith scholars, a mawquf (stopping at a Companion) hadith. Its counterpart is a marfu' (traced to the Prophet) hadith. If we see in a book that a hadith is marfu', that is an abbreviation for their saying: "The Messenger of Allah (peace and blessings be upon him) said." Conversely, if we see in a book that a hadith is mawquf, that is an abbreviation for "So-and-so, the noble Companion, said." Likewise, if it says "narrated as marfu'," it is an abbreviation for "from the Prophet." Likewise, if it says "narrated as mawquf," it is an abbreviation for "from the saying of some of the Companions," and so on.
