a verse of the Quran and vice versa. Distinguishing between which of the two kinds of revelations are involved in abrogating and in being abrogated creates four variations of naskh in this classification: a ruling from a verse of the Quran is abrogated by another conflicting ruling from another verse in the Quran (almost all the examples of naskh mentioned above are this form); a ruling in the Sunnah is abrogated by another conflicting ruling from the hadith (the two examples of Explicit Abrogation mentioned above — visiting graves and storing sacrificial meat — are examples of this form of naskh); a ruling from a verse of the Quran is abrogated by a conflicting hadith (an example being the abrogation of the ayah of bequest in al-Baqarah 2:180 explained below): when a ruling from the Sunnah is abrogated by a conflicting ruling from a verse in the Qur'an (an example being the change in the qiblah from Jerusalem to Mecca, a Sunnah practice abrogated by Q.2:144, also explained below). Regarding variety #3, (Sunnah abrogating the Quran), a consensus of scholars believe that Quranic verse 2:180 — the "ayah of bequest" in al-Baqarah: ...has been abrogated by a hadith included in Sunan Abu Dawood collection. Abu Dawud, Sunan Abi Dawud 2870. "... no bequest must be made to an heir." An example of variety #4, (abrogation of part of the Sunnah by a Qur'anic verse) is found above as an example of Explicit Naskh above — namely what the qiblah (direction facing during salah prayer) should be. This direction was originally Jerusalem/Quds according to hadith included in the collection Sahih al-Bukhari (41) ... when the Prophet first came to Madinah ... he prayed facing towards Bayt al-Maqdis for sixteen or seventeen months." (John Burton notes that there is no reference in the Quran to praying in the direction of Jerusalem.) ... was abrogated by Ayah 144 of Surah al-Baqarah: Arguments on abrogation between sources While abrogation by the same type of revelation — i.e. varieties #1 and #2 — are accepted by all scholars (i.e. all who support the orthodox theory of abrogation), abrogation between types of revelation — #3 and #4 — are not. The scope of Naskh doctrine between sources has been one of the major differences between the Shafi'i and Hanafi fiqhs, with Shafi'i sect of jurisprudence forbidding abrogation by the Sunnah of the Qur'ān, while Hanafi sect
