The following principal types of hadith are important:

• Marfu' - "elevated": A narration from the Prophet (may Allah bless him and grant him peace), e.g. a reporter (whether a Companion, Successor or other) says, "The Messenger of Allah said ..." For example, the very first hadith in Sahih al-Bukhari is as follows: Al- Bukhari === Al-Humaidi 'Abdullah b. al-Zubair === Sufyan === Yahya b. Sa'id al-Ansari === Muhammad b. Ibrahim al-Taymi === 'Alqamah b. Waqqas al-Laithi, who said: I heard 'Umar b. al- Khattab saying, while on the pulpit, "I heard Allah's Messenger (may Allah bless him and grant him peace) saying: The reward of deeds depends on the intentions, and every person will get the reward according to what he has intended; so whoever emigrated for wordly benefits or for a woman to marry, his emigration was for what he migrated.".

• Mauquf - "stopped": A narration from a Companion only, i.e. his own statement; e.g. al-Bukhari reports in his Sahih, in Kitab al-Fara'id (Book of the Laws of Inheritance), that Abu Bakr, Ibn 'Abbas and Ibn al-Zubair said, "The grandfather is (treated like) a father." It should be noted that certain expressions used by a Companion generally render a hadith to be considered as being effectively marfu' although it is mauquf on the face of it, e.g. the following:

"We were commanded to ...".

"We were forbidden from ...".

"We used to do ...".

"We used to say/do ... while the Messenger of Allah was amongst us.".
