Is there abrogation (naskh) and abrogated (mansookh) in the Prophet's Sunnah, and how can the abrogating and abrogated traditions be identified, is it by their date of transmission or by other methods?

The existence of abrogation (nasakh) in the Sunnah and the Qur’an is sound, and the lack of knowledge regarding the dates of some hadiths does not preclude this. Examples of the Sunnah abrogating the Sunnah include the prohibition of temporary marriage (mut'ah) after it was initially permitted. Examples of the Qur’an abrogating the Sunnah include the Almighty's saying: "Call them by [the names of] their fathers," which abrogated adoption, a practice they [the pre-Islamic Arabs] used to follow. There is a difference of opinion regarding the abrogation of the Qur’an by the Sunnah, but the verified position is that it is permissible and has occurred by means of the mutawatir (concurrently transmitted) Sunnah. Examples of this include the abrogation of the verse of five sucklings and the surahs of al-Khal' and al-Hafd.
